Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

Which of these best describes the tiny leg bones that some whales have, which do not aid in their movement or serve any other function?
O structures that grow and improve in function as they are used
O structures that function at certain times of the year or under certain conditions
O structures that will become adaptations when the environment changes
O structures that have lost all or most of their function over evolutionary time
Answer:
D. structures that have lost all or most of their function over evolutionary time
Explanation:
the question states that the leg bones are almost entirely unused because of evolution
The study of change over a period of time is called evolution.
The correct answer of the following is D.
The change in the species over the period of time is called evolution. It is necessary to adapt itself in order to survive in nature.
According to the lamark, it is said that the organs which are no longer used in the body will become vestigial and will be removed from the body over a period of time.
According to the question, the small bones in the whale is might have functioned in the ancestor period but not in the current time due to the course of the evolution.
Hence, the correct answer is D that structures that have lost all or most of their function over evolutionary time.

what is the transfer of pollen from the anther to the stigma of a flower.
Answer:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

A student reads that deer mice that migrated to the hills of Nebraska originally had dark colored
coats. Over many years, due to a mutation, the coat color of the mice changed to a lighter color to
blend in easily with the sand. Which argument summarizes the mutation in deer mice?
a) It is a harmful mutation as it caused a change in the original coat color of mice.
b) It is a beneficial mutation as it helped the mice survive in their new surroundings.
C) It is a neutral mutation as the change in coat color did not affect any body functions in the
mice, and only helped the survival of the deer mice living in Nebraska.
d) It is a neutral mutation as only the deer mice living in Nebraska were affected, and all other
populations were unaffected.
The argument which summarizes the mutation in deer mice is It is a beneficial mutation as it helped the mice survive in their new surroundings.
What is mutation?A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health. Compared to what we typically see in science fiction movies, this is completely different.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings.
Therefore, The argument which summarizes the mutation in deer mice is It is a beneficial mutation as it helped the mice survive in their new surroundings.

Answer:
because plants faces and gets sunlight to grow
Explanation:
horizon.
At night, in its absence, the sunflowers face east again, anticipating the sun’s return.
They do this until they get old, when they stop moving. Then, always facing east, the old flowers await visits from insects that will spread their pollen and make new sunflowers. Those flowers too, will follow the sun.
Which process has evolved to yield the GREATEST variation of offspring?
A.Meiosis
B.Mitosis
C.Replication
Meiosis has evolved to produce the greatest variation of offspring.
What is meiosis?Meiosis is a type of cell division that occurs in eukaryotic cells, such as those in animals and plants, to produce reproductive cells (gametes) that have half the number of chromosomes as the parent cell.
During meiosis, chromosomes pair up and genetic material through a process called crossing over, creating genetic diversity among the gametes. This diversity increases the chances that at least one offspring will be better suited to its environment and increase the survival chances of the species.

Answer:
asteroid belt
Explanation:
region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.
1. An unstable nucleus releases radiation in the form of a helium particle. What process is occurring!
a) Fusion
b) Fission
c) Alpha Decay
d) Beta Decay
An unstable nucleus with too many protons emits energy and an alpha particle during alpha decay. An alpha particle is actually a helium nucleus because it has two protons and two neutrons. A nuclear equation can be used to represent alpha decay. Thus, option C is correct.
What is the alpha decay releases of radiation from helium?When an unstable nucleus changes to another element, a nuclear process called “alpha decay” produces a particle consisting of two protons and two neutrons. The helium nucleus that is being ejected is known as an alpha particle.
An alpha particle is released when a nucleus becomes unstable due to having an excessive number of protons. An alpha particle is a helium nucleus, since it has two protons and two neutrons. This is the alpha decay.
Therefore, Each of the two protons and two neutrons that make up an alpha particle is a helium nucleus that has lost its planetary electrons.

Explain how the sugars, phosphates, and nitrogenous bases in one strand of DNA connect to a complementary strand during replication
Answer: One strand of DNA binds to another via base complementarity.
Explanation:
The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.
The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases.
There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine.
Why are sugar-phosphate and nitrogenous bases important to DNA molecules?The sugar-phosphate backbone is a significant component of DNA's double helix structure.
The structure of DNA is tied to its function. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information.
Thus, base complementary is the reason.
