1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?
Answer:
1. 50%
2. Every gamete only contains 50% of the genetic information or half of the information for a gene.
Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.
2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well
Heterogeneous means different

For this discussion, explain how each organelle in a eukaryotic animal cell is interconnected with the others. You will need to write at minimum a couple of paragraphs but at most as much as it will require for you to answer this.
Answer:
Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.
The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.
There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. Which barrier will then act on the bacteria? chemical physical biological electrical.
Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.
Answer:
[tex]\huge\boxed{\sf Biological}[/tex]
Explanation:
When first and second line of defense is passed by the bacteria, the third line of defense will come into action which is a biological barrier which includes antigen which are anti-bodies generating substances.

what is the primary action of antidiuretic hormone?
Answer:
The primary action of the antidiuretic hormone is that it causes collecting ducts in the kidneys to reabsorb more water.
Explanation:
Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.
What is Anti-diuretic hormone (ADH)?Human vasopressin is also called antidiuretic hormone, arginine vasopressin or argipressin. It is defined as the hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus that converts to AVP.
ADH is the hormone that helps constrict blood vessels and helps the kidneys control the amount of water and salt in the body which helps control blood pressure and the amount of urine. This reduces the amount of urine released and the nature of urine becomes hypertonic which is concentrated. Because of this type of action, vasopressin is known as an antidiuretic hormone.
Thus, Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

Essential Question: What is the relationship between photosynthesis
and respiration?
*Zoom in to the picture for a better view
Answer:
I. Examine Details
1. In what cell organelle does photosynthesis occur? cellular respiration?
Photosynthesis occurs in the chloroplast, while cellular respiration occurs in the mitochondria.
2. What are the three things needed for photosynthesis? Highlight them on the diagram in green.
Sunlight, carbon dioxide, and water
3. What are the two products of photosynthesis? Highlight yellow.
Glucose and oxygen
4. What are the two things needed for cellular respiration? Highlight blue.
Glucose and oxygen
5. What are the three products of cellular respiration? Highlight purple.
Carbon dioxide, water, and ATP
6. What things are recycled (used over and over again) during photosynthesis and respiration?
Carbon dioxide, water, oxygen and glucose
II. Apply (what you already know)
7. Sketch a model of typical plant cell and identify the mitochondria and chloroplasts.
8. What will happen to plants that are kept in the dark?
Plants will die since plants need daylight to deliver food. If there is no admittance to sunlight, the Light Dependent response will not happen.
9. What will happen if you forget to water your plants?
The plants will die since water is a necessary reactant photosynthesis.
10. What happens to animals that are deprived of oxygen?
Those animals will not be able to perform cellular respiration.
III. Big Ideas
11. One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
Obstructing the Sun would cause the powerlessness for essential makers, for example, plants, to go through photosynthesis, in this way not creating its own food fundamental for development and energy.
12. When you walk your dog, you are using energy from the sunlight to power this activity.
Explain. Sunlight gives the energy to essential makers to make their own food, using the carbon dioxide and delivering oxygen gas as a result of photosynthesis. The oxygen that is delivered into the environment is taken in by life forms as a reactant in respiration. Oxygen allows for ATP creation. The ATP is the substance energy structure that is needed to convey all cell processes such as walking your dog.
13. Carefully and completely answer the "essential question" of this activity. Use complete sentences and details from the model to explain your position.
Essential Question: What is the relationship between photosynthesis and respiration?
Photosynthesis and respiration are related since the reactants of photosynthesis are the products of cellular respiration, and vice versa. For example, the reactants of photosynthesis are energy, carbon dioxide, and water, while the products are oxygen and glucose. The reactants of cellular respiration are oxygen and glucose, while the products are energy, carbon dioxide, and water.
