Answer:
0.2
Explanation:
According to Hardy-Weinberg equilibrium,
p + q = 1
p² + 2pq + q² = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² =frequency of recessive homozygous genotype
Here,
total people = 100
crumbly earwax = 64
p² = 64 / 100 = 0.64
p = √0.64 = 0.8
Frequency of the c allele = q
q = 1-p
= 1-0.8 = 0.2
Yes, all birds have feathers. About 9,700 kinds of birds live on earth. All birds have feathers and wings but not all birds can fly. Birds have as many as 25,000 feathers and they shed their feathers at least once a year.
Chemical bonds should be the correct answer choice.
Answer:
10 chromosomes/sister chromatids
Explanation:
Prophase is the first stage of cell division (mitosis). Prior to the cell entering the actual division stage, it undergoes a phase where it prepares its content and most importantly undergo the duplication of its genetic material (DNA). This DNA are found as chromosomes. It undergoes replication of its DNA in the S-phase of interphase stage.
Since Arabidopsis thaliana has 10 chromosomes, and each chromosome holds one DNA molecule, 10 molecules of DNA will be present in the mustard plant's genome. These 10 molecules of DNA will be replicated on another copy of chromosome which is identical to the template. This chromosomes are called SISTER chromatids i.e. replicated chromosome. Each sister chromatids are held together at the centromere and are considered one individual chromosome until they separate during anaphase stage.
Hence, at the Prophase stage, before separation, each sister chromatid (replicated chromosome) is considered as one chromosome. Thus, in the mustard plant with 10 chromosomes, it will possess 10 sister chromatids or chromosomes at the Prophase stage.
N.B: When sister chromatids separate during anaphase stage, they will be regarded as individual chromosomes.
Of the list shown in the image, the function of proteins in living cells are: they transport oxygen in the blood of vertebrates, they play a key role in moving materials within cells, they help the body to recognize and destroy foreign microbes and cancer cells, they catalize chemical reactions.
<h3>What are proteins?</h3>
Proteins are macromolecules made up of linear chains of amino acids that are synthesized by ribosomes using mRNA molecules as templates. they have different functions since they are present in enzymes, hormones, transport proteins and also as a structural part.
Therefore, we can confirm that of the list shown in the image, the function of proteins in living cells are: they transport oxygen in the blood of vertebrates, they play a key role in moving materials within cells, they help the body to recognize and destroy foreign microbes and cancer cells, they catalize chemical reactions.
