Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

A scientist finds that a sample of matter contains three types of atoms. The sample can be any of the following, except:
A. compound
B. molecule
C. element
D. mixture
Answer:
D. mixture
Explanation:
because the mixture is not part of an atom
As per the given scenario, the sample can be any of the following, except element. The correct option is C.
What is an element?A substance that is unable to broken down chemically into smaller molecules.
An element is made up of atoms with the same atomic number, which means that each atom possesses the same count of protons in its nucleus as the other atoms in the element.
A chemical compound is a chemical substance made up of many identical molecules made up of atoms from multiple elements that are held together by chemical bonds.
A molecule made up of only one element's atoms is thus not a compound.
A scientist discovers three types of atoms in a sample of matter. Except for elements, the sample can be any of the compound, molecule or mixture.
Thus, the correct option is C.

c
Cell A shows active transport and Cell B shows diffusion
d

Answer:
C I think
Explanation:
Cell A shows active transport and Cell B shows diffusion in the given diagram.
What are the types of transport methods?
All higher organisms, including humans, animals, and plants, go through a process called transportation that is necessary, natural, and part of their physiological makeup. To support life, this interaction is significant as it capabilities by continually shipping, different fundamental materials to and from all pieces of the body including cells, tissues, and organs.Water, hormones, gases, mineral nutrition, organic material, and other things are the primary essential materials. An organism's various modes of transportation include:Active transport Passive transport Facilitated transportDiffusion.The term "active transport" refers to a process in which molecules use external energy to move from a lower concentration area to a higher concentration area against a gradient or obstacle.Any substance's overall movement from a higher concentration area to a lower concentration area is known as diffusion. This can occur between cells or within them. Due to the random movement of their particles, only gases and liquids experience diffusion. It is an essential biological process. It is how things enter and exit cells. It occurs naturally and does not call for any energy.The container or the particles themselves come into contact with one another. In the end, the particles cover the entire container. There is no stirring, shaking, or wafting during diffusion.We refer to this as the concentration gradient down because diffusion is the movement of particles from a higher concentration to a lower concentration.

A lake in Minnesota was thriving with black bass and bluegill. These particular fish build nests on the sandy bottom of the lake. Now, ecologists are finding that over time a layer of humus has slowly been covering the pond. The ecologists are noting that the populations of black bass and bluegill are declining, and the fish that are able to make nests in humus are rising in numbers.
The ecologists can probably conclude that this event is an example of:
commensalism
parasitism
primary succession
succession
Answer:
Explanation:
https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession
The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.
Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.
In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.
The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.
The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.
Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

Answer:
(D)-The circulatory system
Explanation:

The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.
What is Circulatory System?The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.
The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.

Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.

The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

The relationship between catabolism and anabolism is most similar to the relationship between which of the following pairs of terms?
free energy, entropy
exergonic; endergonic
exergonic; spontaneous
work, free energy
Answer:
The pair of terms whose relationship is very similar to the relationship between catabolism and anabolism are exergonic and endergonic.
Explanation:
Anabolism and catabolism are processes that occur in matabolism, whose result is different.
Anabolism involves all the processes of manufacture or synthesis, in which chemicals are bound together to form new compounds. This process consumes energy, so it is called endergonic. Catabolism, unlike anabolism, is the process of degradation of complex molecules into simple molecules. One of the results of catabolism is the release of energy, which is equivalent to saying that it is an exergonic process.Relating catabolism to anabolism is similar to relating exergonics to endergonics.
The other terms do not represent a similarity with the relationship between the processes of catabolism and anabolism.
