Each of two parents has the genotype brown/red, which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child. Assume that if the child has at least one brown allele, that color will dominate and the child's hair color will be brown. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have the red/red genotype? c. What is the probability that the child will have brown hair color? a. List the possible outcomes.
Answers
Answer:
a. In image attached.
b. 25% or a 1 in 4 chance.
c. 75% or a 3 in 4 chance.
Explanation:
B = Dominant (brown gene)
r = Recessive (red gene)
If two parents both have Br genes, they will both have brown hair.

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios in progeny resulting from the following crosses.a.LMLM x LMLNb.LNLN x LNLNc.LMLN x LMLNd.LMLN x LNLNe.LMLM x LNLN
Answers
Answer:
Please find the expected genotypes and phenotypes of the progenies of each cross below.
Explanation:
In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).
Considering the following crosses (find the punnet square attached);
a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)
b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)
c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L
Blood type MN (2) : Blood type N (1)
d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)
e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)

c. Lightning strikes a tree and begins a fire that clears the land.
d. Ticks infesting moose weaken the moose's health and reproductive success.
e. Frigid temperatures flow into the area, causing hypothermia and death.
Answers
Answer: Option B and C.
Heavy and continuous rains flood the land, submerging habitats.
c. Lightning strikes a tree and begins a fire that clears the land.
Explanation:
Heavy and continuous rains flood the land, submerging habitats.
Lightning strikes a tree and begins a fire that clears the land.
The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.
Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.
Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.
Therefore, Heavy and continuous rains flood the land, submerging habitats.
cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
The scenarios that describe an abiotic factor that is density independent are ; ( B and C )
Heavy and continuous rains flood the land, submerging habitats ( B )Lightning strikes a tree and begins a fire that clears the land ( C )Abiotic factors are Nonliving components of an ecosystem that has a significant effect on the ecosystem such as ; Rain, rocks, Temperature and humidity. Density Independent factors are factors in an ecosystem that can cause the decrease or increase of the population size of an ecosystem.
Heavy and continuous rainfall is an abiotic factor that has the ability to decrease the population of an ecosystem by submerging organisms habitats.
Lightning striking a tree and setting it ablaze which clears the land also reduces the population of the ecosystem because the fire will lead to loss of habitats and death of some organisms .
Hence we can conclude that The scenarios that describe an abiotic factor that is density independent are Heavy and continuous rains flood the land, submerging habitats and Lightning strikes a tree and begins a fire that clears the land .

4. In terms of base composition, the %T = %G.
5. This contains the sugar ribose.
6. The sugars are connected with a 3'-5' phosphodiester link.
7. It contains equal amounts of guanine and cytosine.
8. Bases are attached to sugars in an alpha N-glycosides linkage.
Answers
Answer:
DNA
It can contain the purine adenine
This contains the pyrimidine thymine
The sugars are connected with a 3'-5' phosphodiester link.
It contains equal amounts of guanine and cytosine. The percentage of A-T ,C-G are the same in DNA,,they are linked by hydrogen bonds.But varies in RNA.
Explanation:
.RNA
It can contain the purine adenine.
It can contain the pyrimidine uracil
This contains the sugar ribose. This is a 5C sugar with one oxygen atom deficient.The forms the lever for holding the bases and phosphate group
The sugars are connected with a 3'-5' phosphodiester link.This is the backbone of both DNA and RNA.It is formed between the sugars and the phosphate groups in both DNA and RNA.
None is made of base composition, the %T = %G. This is wrong because purines must pair with pyrimidine,but not two purines or pyrimidine pairing as shown,
Bases are attached to sugars in an alpha N-glycosides linkage.This is wrong the beta N-glycisidic bonds are the linkages

We can find four principal layers composing the digestive tube walls. From the lumen to the exterior: Mucosa, Submucosa, Muscle, and Serosa Layers.
-----------------------------
There are four principal layers composing the digestive tube walls.
From the lumen to the exterior of the tube, we can find,
Mucosa Layer
Composed of lining epithelium, a propria lamina of connective tissue, and a smooth muscle layer.
The epithelium works as a barrier that separates the lumen from the organ.
Propria lamina has glands, vessels that get the absorbed substances, and immune system elements.
The smooth muscle delimitates the mucose from the submucosa layer. It produces movements that are independent of the rest of the organ's movements.
Submucosa Layer
Dense connective tissue is placed under the mucosa.
It has bigger vessels that ramification to the mucose, muscle layer, and serosa layer.
In certain areas, this layer also has glands.
Muscle Layer
Composed of two or three concentric smooth muscle layers that differ in their orientation.
The contraction of these layers mixes and propels the content of the lumen of the digestive tube.
Serosa layer
Connective tissue membrane covered by simple plane epithelium.
High caliber vessels are placed in this layer and limphatic vessels.
There are regions of the digestive tube where there is no serosa layer. Instead, there is a connective tissue named the adventitious layer.

You are observing a sample of cells in the lab to determine why they did not
divide properly. You notice that the chromosomes are lined up in the middle
of the cell, and the spindle fibers have extended towards them, but have not
attached. What could be damaged?
Answers
Explanation:
What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome.
