Hox genes are regulatory genes in multicellular animals that code for transcription factors that determine the basic body plan in a developing embryo. They act as switches that turn other genes on and off. Scientists have found that a mutation in a fruit fly hox
gene produces flies with legs instead of antennae sticking out of their heads. Another hox gene mutation results in fruit flies with
two pairs of wings instead of one pair. Hox genes affect body plans by controlling the expression of many other genes
Many multicellular animals have the same hox genes. Which statement is evidence for this claim?
(1 point)
O There is a wide variety of body plans in complex animals.
o The body plans of complex animals are very similar to one another
The body plans of complex animals change over generations
The body plans of complex animals typically have a large number of mutations.

Answers

Hi! Welcome to Brainly! Thanks for asking a question!

So, based on the options provided in the question above, the correct option would be 'the body plans of complex animals are very similar to one another' or in other words Option B or 2.

Hope this helped! Happy holidays!

The correct option is The body plans of complex animals change over generations.

What are hox genes?

Hox genes are important regulators of how the animal body plan is organized. They contain transcription factors that when combined can give instructions to cells at various body levels on their potential morphological contributions.

In addition to its historical role in the anterior-to-posterior (AP) axis, HOX proteins also help to organize secondary axes and a number of different organs and tissues. Hox genes are grouped together in the genomes of many species that exhibit bilateral symmetry.

Because the sequence of genes in cis inside the cluster corresponds to the order of their expression domains along the various axes, this specific genomic architecture has functional significance.

Therefore, The correct option is The body plans of complex animals change over generations.

A large protein needs to enter a cell to help preform a function explain what process the cell must use to allow the protein to enter and why

Answers

Answer:

The protein is too large to simply diffuse across the phospholipid bilayer of the cell, so it uses phagocytosis to diffuse across, where it is contained in a vesicle and pinched into the cell? Credits to yahoo answer. Hope I could help sweets.

Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.

These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.

In which type of fault is the hanging wall above the footwall?

normal

strike-slip
horizontal

Answers

Answer:

B. Reverse

Explanation:

Got it right on edge

A hanging wall and footwall are present in every fault that is inclined from vertical. In reverse type of fault is the hanging wall above the footwall. Therefore, option B is correct.

What is footwall ?

The higher or overlaying block along the fault plane is referred to as the hanging wall, or headwall, and the block below is referred to as the footwall as rocks slide past one another during faulting. The direction in which the fault plane and Earth's surface collide is known as the fault strike.

The rock above the fault zone in a cross-section view of a fault is referred to as the hanging wall.The foot wall refers to the rock beneath the fault zone.

Consider digging a mine along the fault line to help you distinguish between the two. The footwall is the brick directly beneath your feet, and it is also the one on which you would hang your miner's lantern.

Thus, option B is correct.

A.
Some use H2O (water), and others do not.
B.
Some use CO2 (carbon dioxide), and others do not.
C.
Some use air, and others do not.
D.
Some use O2 (oxygen), and others do not.

Answers

Answer:

D. Some use O2 (oxygen), and others do not.

Explanation:

Bacteria can either grow aerobically or anaerobically. Because of their ability to respire and ferment organic substances, these types of bacteria (facultative anaerobes), can continue growing in the presence or the absence of oxygen.

Hope this helps! Please Mark BRAINLIEST.

Answer:

They would perform aerobic processes.

Explanation:

When exposed to a lack of oxygen, facultative anaerobes develop metabolic processes with oxygen, like respiration. But in the absence of oxygen, they can develop processes like fermentation. When in oxygen, they prefer the use of it, because that's what makes them facultative, the fact that they're able to work in both circumstances. Otherwise, tolerants are able to survive but not to work properly, in different environments.

what will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?

Answers

A cell that completed mitosis but does not undergo cytokinesis PRODUCES one cell with two nuclei, each identical to the nucleus of the parent cell. Cytokinesis is the last phase of cell division.

Cytokinesis is the process by which a parental cell divides its cytoplasm to produce two genetically identical daughter cells, each one containing one cell nucleus.

Cytokinesis occurs in both types of cell division, i.e., mitosis and meiosis.

In animal cells, cytokinesis occurs by the emergence of a contractile ring that appears just beneath the cell membrane.
