Animals which have ranging which is from corals to monkeys they have presence of Hox genes in common.

Hox genes are examples of homeotic gene. They are group of genes which have genes which are related and they do control the plan of the body.

If the segments of embryo are being formed then the determinants of wings, antennae and legs is the Hox protein.

Unfortunately this question is incomplete as it is a multiple choice question. The following options are provided:
A) body cavity between body wall and digestive system
B) number of embryonic tissue layers
C) type of body symmetry
D) presence of Hox genes
E) degree of cephalization

The answer is D: presence of Hox genes

Hox genes are a group of genes that determine the basic structure and orientation of animals.

A man and a woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7

ValentinkaMS [17]

Answer:

Pr= (3/16)

Explanation:

It was stated that both the man and the woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7).

∴ let Aa¹Bb° represent the traits in the Man

Where;

Aa¹ = carrier of PKU

Bb° = carrier of cystic fibrosis

Also, let Cc¹Dd° represent the traits in the woman

Where;

Cc¹ = carrier of PKU

Dd° = carrier of cystic fibrosis

Now, if Aa¹Bb° self-crossed, we'll have the F1 progeny as AB, Ab° , a¹B and a¹b°

also, if Cc¹Dd° self-crossed, we have CD, Cd° , c¹D and c¹d° as their F1 progeny

In the F2 generation, the dihybrid cross between the F1 generations will be:

AB, Ab° , a¹B, a¹b° × CD, Cd° , c¹D, c¹d°

ACBD, ACb°D, a¹CBD, a¹Cb°D

ACBd°, ACb°d°, a¹CBd°, a¹Cb°d°

Ac¹BD, Ac¹b°D, a¹c¹BD, a¹c¹b°D

Ac¹Bd°, Ac¹b°d°, a¹c¹Bd°, a¹c¹b°d°

Only (a¹CBD, Ac¹BD, a¹c¹BD) shows the probability that she will have PKU but not CF.

G) type of adherens junction connecting cells with the extracellular matrix. focal adhesion

H) intermediate filaments associated with plaques. Tonofilaments

I) collection of adherens junctions particularly associated with epithelial cells.

J) type of adhesive junction containing actin microfilaments. Adherens junctions

K) specialized modifications of the cell membrane in which two cells come together in multicellular organisms. Cell junctions

L) point of cytoplasmic contact between two cells. Gap junction

M) anchors cytoskeleton of one cell with that of a neighboring cell. Adhesive junction

Explanation:

Connexin: is a transmembrane protein that forms the gap junctions, they are also called gap junctions proteins.

Hemidesmosome junctions: these types of junctions are in the epidermis, specifically between the epithelial cells and the basal lamina of the epidermis.

Plaque: they are part of the adherens junctions, they are fibrous proteins that are attached to certain points of the extracellular matrix.

Tight junctions: are junctions between two epithelia, they are very restrictive and do not allow the passage of soluble molecules creating a permeability barrier.

Desmosomes: are very strong cell to cell junctions on the lateral sides of plasma membranes. They are in tissues that are under mechanical stress, such as the cardiac muscle.

Connexons: is a pore made of six connexin proteins in a gap junction. Connexons are the ones that connect two cells in gap junctions.

Focal adhesions: They connect the extracellular matrix with the cell, regulatory signs and mechanical force is transmitted through them.

Tonofilaments: tonofilaments are the ones that are associated with a plaque in adherens junctions, they are in epithelial tissues.

Adherens junctions: are cell to cell junctions where the cytoplasmatic face is connected to the actin cytoskeleton. They appear as spots forming the plaque or as zonula adherens, which are actin bands around the cell.

Cell junctions are protein complexes that connect two cells that are next to each other or a cell with the extracellular matrix. They have a lot of functions, such as pas information from cell to cell, or the exterior, form a barrier, synchronize cells, etc.

Gap junctions: are connections between the cytoplasm of two cells, molecules and, ions pass directly from one cell to the other.

How could the urban area on the map pose a threat to the everglades

stellarik [79]

The encroaching urban areas could harm the wildlife around and in the everglades because of the fear of wildlife (people could shoot the animals) possible expansions could cause deforestation, and human pollution could kill off plants and animals.
