Answers

Answer 1

Immovable joints cartilage plate interposed, in slightly moveable joints cartilage plate symphysis whereas in freely moveable joints cartilage plate allows movement in two plains.

Joints are practically named unflinching (­synarthrotic), marginally portable (amphiarthrotic), or uninhibitedly mobile (diarthrotic). Less portable joints for the most part have greater steadiness. They can likewise be structurally­ gathered by the sort of tissue ­binding them at their intersections, for example, stringy, carti-laginous, and synovial joints. By and large, stringy joints are enduring, though synovial joints are uninhibitedly versatile. Cartilaginous joints might be either inflexible or somewhat mobile.

Immovable joints are those that don't permit development (or take into account, without a doubt, extremely slight development) at joint areas. Bones at these joints have no joint hole and are kept intact fundamentally by thick stringy connective tissue, typically collagen. These joints are significant for soundness and security.

Slightly moveable joints offers help for bones while taking into consideration restricted development. These are significant capabilities as it connects with the spinal section as spinal vertebrae help to safeguard the spinal line.

Freely moveable joints are grouped primarily as synovial joints. Not at all like stringy and cartilaginous joints, synovial joints have a joint cavity (liquid occupied space) between interfacing bones.

# SPJ4

Six molecules of carbon dioxide are necessary to make one molecule of glucose during the process of photosynthesis.

The overall chemical equation for this process is:

6CO2 + 6H2O + light energy = C6H12O6 + 6O2

where CO2 is carbon dioxide, H2O is water, and C6H12O6 is glucose.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

The majority of land animals were dinosaurs. much of the Cretaceous period saw higher sea levels than at any other time.

The final stage dinosaur extinction was caused by an asteroid collision rather than volcanism. As a result of an accelerated plate collision that occurred during the Cretaceous, mountains grew along North America's western border. The Gulf coast basin began to recede as these mountains rose, and seawater started to move northward into the increasing western interior. The Arctic region also started to flood with marine water.

Which type of secretion has an extracellular effect such as the digestion of food?Multiple choice question.ExocrineEndocrine

Answers

Exocrine secretion is the type of secretion that has an extracellular effect, such as the digestion of food.

Exocrine glands secrete their products into ducts, which then transport the secretions to the site of action. Examples of exocrine glands include the salivary glands, the pancreas, and the glands that secrete digestive enzymes into the small intestine. These secretions act outside of the cell and have a direct effect on the external environment.

Digestion is a good example of an exocrine function, where enzymes are secreted by glands such as the pancreas and salivary glands into the small intestine to break down food molecules. The enzymes secreted by these glands are not only specific to certain types of molecules but also specific to certain regions of the gut, thus ensuring an optimal digestion.

On the other hand, endocrine glands secrete hormones that act on target cells through the bloodstream, which have a more systemic effect.

Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation

Answers

HIV/AIDS is an infectious disease caused by the Human Immunodeficiency Virus which causes severe damage to the immune system.

1. How is HIV transmitted?

HIV is most often spread through unprotected sexual intercourse, as well as through blood transfusions and sharing of needles or syringes contaminated with HIV-infected blood.

It is also possible for a mother to pass HIV to her child during pregnancy, childbirth, or breastfeeding. However, activities such as hugging, shaking hands, or using the same toilet are not known to transmit HIV. HIV can be easily spread through contact with infected bodily fluids such as semen, vaginal fluids, or blood.

2. What are the signs and symptoms of HIV?

At the initial stages of HIV infection, one may experience flu-like symptoms such as fever, headache, swollen lymph nodes, joint and muscle pains, rash, and sore throat. As the virus progresses, more advanced signs may arise, such as extreme fatigue, sudden weight loss, yeast infections, shingles, and fever lasting more than 10 days.

3. What is the distinction between HIV and AIDS?

HIV is a virus that can weaken the immune system over time, and if left untreated can lead to AIDS. AIDS is the most advanced stage of HIV infection and is characterized by the presence of certain illnesses and a weakened immune system. HIV itself does not cause any symptoms, but can eventually cause a person's immune system to weaken to the point that they develop AIDS.

4. What medications are used to treat HIV?

Antiretroviral therapy (ART) is the main form of treatment used to manage HIV. This treatment uses a combination of medications that work to reduce the amount of virus in the body to an undetectable level, stopping it from replicating and spreading. By achieving this undetectable level, the risk of transmitting HIV to others is greatly reduced.

If an average lake trout weighs 4,500 g, what is the total mass of PCBs in a trout in the Great Lakes?

Answers

The amount of PCBs in a trout in the Great Lakes can vary drastically based on the specific lake and the age and health of the fish. Generally, PCB levels are much higher in the older, larger fish, and as such, the total mass of PCBs in a 4,500 g lake trout in the Great Lakes can range from 1-7 mg. However, due to the large size of the trout, the total mass of PCBs can be as much as 7 mg, which is enough to negatively affect its health.

PCBs (polychlorinated biphenyls) are a man-made chemical compound found in many environments, including the Great Lakes. PCBs have been linked to a variety of health concerns, including cancer and reproductive problems. As such, they are of great concern in the Great Lakes, where they are known to bioaccumulate in fish.

To calculate the total mass of PCBs in a lake trout in the Great Lakes, one must first determine the average concentration of PCBs in lake trout in the Great Lakes. The United States Environmental Protection Agency (EPA) has established an acceptable concentration of PCBs in the Great Lakes of 0.09 parts per million (ppm). Therefore, an average lake trout in the Great Lakes contains 0.09 ppm of PCBs.

The total mass of PCBs in a lake trout in the Great Lakes can then be calculated using the following equation:

Total mass of PCBs (in grams) = (Average lake trout weight) x (Average PCB concentration in the Great Lakes)

Therefore, for an average lake trout weighing 4,500 g, the total mass of PCBs in the Great Lakes would be 4,500 x 0.09 = 405 g.

indicate some mechanisms by which hormones exert their effects.

Answers

Hormones exert their effects through a variety of mechanisms, such as Receptor-mediated signaling, Second messenger systems, Gene regulation, Ion channel modulation, Enzyme modulation.

A) Receptor-mediated signaling: Hormones bind to specific receptors on the surface or within cells, triggering a cascade of chemical reactions that lead to a cellular response. For example, insulin binds to receptors on the surface of cells in the liver, muscles, and fat tissue, triggering the uptake of glucose from the bloodstream.

B) Second messenger systems: Hormones can activate second messenger systems, which amplify the signal and transmit it to the target cell. For example, the hormone adrenaline binds to receptors on the surface of cells, triggering the release of the second messenger cyclic AMP (cAMP), which leads to an increase in heart rate and blood pressure.

C) Gene regulation: Hormones can also regulate gene expression by binding to receptors on DNA or interacting with transcription factors. This can lead to the synthesis of new proteins, which in turn can affect cell growth, metabolism, and other functions. For example, the hormone estrogen can bind to receptors on DNA and activate the expression of certain genes, leading to the growth and development of female reproductive organs.

D) Ion channel modulation: Hormones can also exert their effects by modulating the activity of ion channels. For example, the hormone acetylcholine binds to receptors on nerve cells, causing the opening of ion channels and leading to the release of neurotransmitters.

E) Enzyme modulation: Hormones can also regulate the activity of enzymes. For example, thyroid hormones can increase the activity of enzymes involved in metabolism and energy production

how can having a large population keep the population in hardy weinberg equilibrium

Answers

The Hardy-Weinberg equilibrium is a theoretical model that describes genetic makeup of a population in equilibrium. Equilibrium is maintained by the balance of five factors: mutation, selection, migration, genetic drift, and random mating.

How can having large population keep the population in Hardy Weinberg equilibrium?

One of the factors that can prevent the population from deviating from Hardy-Weinberg equilibrium is large population size. This is because in  large population,  effects of genetic drift are greatly reduced. Genetic drift is the random fluctuation of allele frequencies that occur in small populations and can lead to a deviation from Hardy-Weinberg equilibrium.

In a large population, any random fluctuations in allele frequencies are likely to be small and quickly counterbalanced by large number of individuals carrying different alleles. So, large population reduces the chance of genetic drift and thus maintain the equilibrium.

The plane which separates the body into superior and inferior portions is referred to as the transverse plane. It is also known as the axial plane. The superior and inferior are the upper and lower portions of the body respectively.

A cross-sectional plane or horizontal plane is the other name referring to the transverse plane. In contrast, a coronal or frontal plane divides the body into anterior and posterior sections. In general, the planes are the imaginary flat surfaces that span the body parts. The frontal, sagittal, and transverse planes are all at right angles to one another. Sections are cuts made along a plane across the body or its organs. All the names are based on the plane along which the cut is made.

What are the similarities of Effect of the temperature on yeast respiration experiment?​

Answers

Answer:

Read below:

Explanation:

Similarities of an experiment that looks at the effect of temperature on yeast respiration may include:

Measuring the rate of respiration: This can be done using a gas sensor or a respirometer to measure the production of carbon dioxide.Keeping other variables constant: To ensure that the results of the experiment can be attributed to the effect of temperature, it is important to keep other variables such as the concentration of yeast, the concentration of sugar, and the amount of oxygen in the environment constant.Using a range of temperatures: To observe the effect of temperature on yeast respiration, the experiment should use a range of temperatures, such as room temperature, warm temperatures, and cold temperatures.Using a control group: To ensure that the results of the experiment can be attributed to the effect of temperature, it is important to use a control group, which is exposed to the same conditions as the experimental group, but at a constant temperature.Repeating the experiment multiple times: To ensure the results are reliable and accurate, it is important to repeat the experiment multiple times using the same methods and conditions.

Darwin compared the fiches with their environment. He connects them with how finches differ because of their food source availability and how they have thrived on the Island.

Darwin was the first person to observe the differences in finches in the Galapagos Islands. He observed small sparrow-like back birds that are strong with short beaks. These are referred to as Darwin's finches. These finches differ in their beak shape and size. He concluded that the species of finches that have adapted over time have different beaks to acquire foods from different sources. So from this experiment, he compares the geology and finches as follows:

Most of the species of birds found on the Island were finches.He also believed that they have adapted to changes over time concerning the environmentHe also states that the species of finches that adapt to the island were able to thrive where others did not.
