Pat wants to measure the length of a table. She'll use a measuring tape. Which units should Pat use to express the length?

Write the hardy-weinberg equation and list the conditions a population must meet to maintain the hardy weinberg equilibrium. exp

Artyom0805 [142]

1. $p^{2} +2pq+q^{2} =1$ where in a population:

p - the frequency of the <em>A</em> allele

q - the frequency of the <em>a</em> allele

$p^{2}$ - the frequency of the <em>AA</em> homozygous genotype

$q^{2}$ - the frequency of the <em>aa</em> homozygous genotype

2pq - the frequency of the <em>Aa</em> heterozygous genotype

A population at equilibrium will have the sum of all the alleles at the locus equal to 1.

2. Conditions:

A. The breeding population must be large

B. No natural selection

C. The mating must occur randomly

D. No mutations to cause changes in allelic frequency.

E. No changes in allelic frequency due to immigration or emigration.

3. By comparing the actual genetic structure of a population with what we would expect from a Hardy-Weinberg equilibrium, we can determine how much it deviates from the baseline provided by the mathematical model. Depending on how large the deviation is, one or more of the model's assumptions are being violated. Thus, we can attempt to determine which one.

The CNS is vulnerable. There are several systems and structures in place which protect these vital tissues. How is the brain and

V125BC [204]

Answer:

1) Skull and Vertebral column

2) Meninges

3) Cerebrospinal fluid.

Explanation:

Central Nervous system:

CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord

Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes

1) Skull and Vertebral column:

Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.

2) Meninges:

These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.

3) Cerebrospinal fluid:

This fluid is present inside meninges which nourishes the brain and protect it from mechanical stresses.

QUESTION 1 (5 marks) A molecule of messenger RNA (mRNA) has just been synthesized and processed in the nucleus of human cell wit

Dmitry [639]

1) DNA Template strand: TACAATCGACCCATC. 2) Anticodon: AAU. 3) mRNA carries genetic information to build the protein. 4) 5 amino acids. 5) Amino acids: Met, Leu, Ala, Gly, Tyr.

1)

<h3>What is the template strand?</h3>

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments:

The coding strand that goes in 5' to 3' direction
The complementary strand -template strand- that grows in 3' to 5' direction .

The template strand is the one that is going to be complemented by the mRNA.

mRNA ⇒ AUGUUAGCUGGGUAG

DNA ⇒ TACAATCGACCCATC

Remember that pairs are as follows

T → A

A → U

G → C

2)

<h3>What is an anticodon?</h3>

The anticodon is the sequence of three nucleotides that couples with the mRNA codon.

Each tRNA has two important sites. One of them is the anticodon that couples with the codon of the mRNA molecule. The other one carries the amino acid that is going to be addeded to the protein.

1st 2nd 3th 4th 5th

mRNA codons ⇒ AUG UUA GCU GGG UAG

tRNA anticodon ⇒ AAU

3)

<h3>What is translation?</h3>

Translation is the stage of protein synthesis during which mRNA carries genetic information needed to synthesize the new protein in the cytoplasm.

Steps,

1- The formed mRNA moves to the cytoplasm through the nucleus membrane pores.

2- Once in the cytoplasm, mRNA meets a ribosome, the primary structure for protein synthesis.

3- Ribosomes are organelles composed of the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

4- While the ribosome reads mRNA strain from its 5' extreme to 3', tRNA adds the correct amino acids to build the polypeptide.

The function of mRNA during translation is to take genetic information needed to build the protein.

4)

<h3>How many amino acids are determined per codon?</h3>

Each codon codes for only one amino acid.

There are cases in which different codons code for the same amino acid, but a single codon always codes for one amino acid.

mRNA codons ⇒ AUG UUA GCU GGG UAG

Amino acids ⇒ Met Leu Ala Gly Tyr

1 2 3 4 5

This mRNA segment represents 5 amino acids.

5)

Amino acids ⇒ Met Leu Ala Gly Tyr

eimsori [14]

Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>

<u></u>

The process by which an embryo transforms into a fetus is known as embryogenesis.
The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.
