Answer:
innervation of the upper limbs
The brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.
What is the brachial plexus?It is responsible for providing the motor (muscle), sensory and sympathetic innervation of the upper limb.
Through it, the spinal cord is connected with all the peripheral nerves of the upper limbs and all the sensorimotor information of these segments is also transmitted.
Therefore, we can conclude that the brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
Select all that apply
O
A
AB
B
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

Lymph capillaries Lymph capillaries filter lymph. originate as closed-ended tubes associated with blood capillary networks. cannot be discerned structurally from cardiovascular system capillaries. include layers of smooth muscle for peristalsis. concentrate lymph prior to passing it to larger lymphatic vessels.
Answer:
The correct answer is ''originate as closed-ended tubes associated with blood capillary networks.''
Explanation:
The lymphatic vessel system begins within the tissues in the form of tubes closed at one end called lymphatic capillaries (chyliferous in the intestine). These have an internal endothelial lining, similar to that of blood capillaries. These vessels are found in greater numbers in the skin, the digestive tract, and the respiratory system. The tissue fluid penetrates the lymphatic capillaries by diffusion, with the help of a small indirect pressure gradient, which gives it the arterial pressure. The walls of the lymphatic capillaries offer little resistance to the entry of substances; they are more permeable than capillaries in the blood system. The tiny capillaries form larger vessels, similar to the venules and veins of the blood vessel system. The walls are thinner than those of the veins of the blood system and its valves much more numerous.

Bumblebees show some ability to control their own body temperature. During cold weather, bumblebees have been observed warming their flight muscles by shivering. The bees are able to maintain a body temperature several degrees above that of the surrounding air. Regulation of their internal body temperature is an example of A. diffusion B. synthesis C. respiration D. Homeostasis
Answer:
D. Homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Hence, regulation of the internal body temperature of the bumblebee is an example of homeostasis.

You are testing learning and memory in two strains (A and B) of hamsters by determining which hamsters learn and remember how to navigate a maze better. You discover that a strain of hamsters raised in a diverse environment has enhanced memory compared to a strain of hamsters raised in a bare cage. You look at a specific gene that is involved in brain development and is activated during learning and memory. If you use bisulfite treatment and subsequent sequencing to study the methylation pattern is of the promoter for this gene, you find that at the same region of the promoter sequence:
Strain A has the following bisulfite treated sequence: GTACGTTAAACGATCG
Strain A has the following untreated sequence: GTACGTTAAACGATCG
Strain B has the following bisulfite treated sequence: GTATGTTAAATGATTG
Strain B has the following untreated sequence: GTACGTTAAACGATCG
Based on the sequences above, greater levels of transcription for this learning and memory gene more likely occur in which of the strains?
Answer:
The correct answer is - Strain B.
Explanation:
The methylation process is adding the methyl group to the DNA molecule that can alter the activity of the DNA segment without any change in the sequence. Methylation presence in the promotor in a gene can repress the transcription process.
By the sequence given it is clear that strain B is not treated and less likely to methylated whereas strain B is more likely to methylated so the greater transcribe sequence would be - Strain B.
How does the shape of the red blood allow diffusion to occur efficiently
Answer:
The partial pressure of oxygen determines the affinity of hemoglobin for oxygen. Red blood cells have the shape of a flattened disk, generating a broad surface area for the diffusion of oxygen. Since their only purpose is carrying oxygen throughout the body, they lack many typical cell structures, including a nucleus.
Explanation:
Hope this helps
Answer:
* Because of their viscoelastic characteristic, red blood cells are able to squeeze through very thin capillaries in order to deliver oxygen and remove carbon dioxide. * The biconcave shape of red blood cells helps maximize the overall surface area required for oxygen absorption.
Explanation:
Suppose we have access to the four nucleotides which compose DNA: A, T, C and G. Placed into a sequence with one another, they form a code which can be read by the cell to provide a blueprint for the creation of proteins. When forming a sequence of three nucleotides, the sequences TAA, TAG, and TGA are codes to tell the cell to stop reading the DNA. Assume each sequence of nucleotides is equally likely to be formed.
A. How many possible ways are there to form a sequence of three nucleotides? - 64
B. Of the possible ways to form a sequence of three nucleotides, what is the probability to form a stop sequence? = 0.0469
C. What is the probability that a sequence that is not a stop sequence is formed? 64-3 = 61 61 = 0.983
D. For a three-nucleotide sequence, G is engineered to be in the third place. For the remaining two nucleotides in the sequence, C cannot be in the second place (for example CTG is allowed but not TCG). How many sequences can be formed?
E. Of the number of sequences found in Part D, what is the probability that a stop sequence is formed?
Answer:
The correct answer is :
A. we know there are four nucleotides and three sequence makes a triplet code then total possible ways are:
4^3 = 4×4×4= 64 ways.
B. The stop codons by 64 amino acid or triplet codes: TAA, TAG, and TGA then the probability would be = 3/64 = 0.0469
C. the probability that a sequence that is not a stop sequence is formed = total minus probability of stop codons:
64-3 = 61
61/64 = 0.953
D. G at end place and c should not be in the middle then:
the codes will be =
ATG
AGG
AAG
TTG
TGG
TAG
CTG
CGG
CAG
GTG
GGG
GAG
Total 12 triplet code sequences.
E. Among all these 12 codons there is only one stop codon that is TAG so the probability of this stop codon is :
1/12 = 0.083

biological classification is important because it allows scientists to study organisms in a ___ way
Answer:
Systematic.
Explanation:
Biological classification is important because it allows scientists to study organisms in a systematic way.
In Science, this biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.
Hence, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

Why is it difficult to avoid a tsunami?
Answer:
It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.
Explanation:
However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.
Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.
