Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).

Emily has a maternal grandfather who is colorblind, which is an X-linked
recessive trait. Everyone else in her family sees normally. Emily's mom is
expecting a new baby girl. What is the chance that the new baby will also
be colorblind?
A. There is no chance that the new baby girl could be color blind.
B. There is no way to determine this from the information provided.
C. There is a 25% chance that the new baby girl will be colorblind.
D. There is a 50% chance that the new baby girl will be colorblind.
Answer:
A
Explanation:
the father doesn't have the trait and since it's recessive, there's no way the baby could have it even if the mother carries it from the grandfather.
There is a 25% chance that the new baby girl will be colorblind. Therefore, the correct option is C.
What is colorblindness?Color blindness is an X-linked recessive trait. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is expressed only when there are two copies of the gene, one on each X chromosome, in females. Males have only one X chromosome, so they will express the trait if they inherit the colorblind gene.
In Emily's family, her maternal grandfather is colorblind. This means that Emily's mother is a carrier of the colorblind gene, since she does not have the trait herself. Emily's father must have two normal copies of the gene, since he does not have color blindness.
When Emily's mother and father have a child, there are four possible combinations of their genes that the child could inherit:
Normal X from mother, Normal X from father (25% chance)
Normal X from mother, Colorblind X from father (25% chance)
Colorblind X from mother, Normal X from father (25% chance)
Colorblind X from mother, Colorblind X from father (25% chance)
Only the last combination would result in a colorblind female, since she would have two copies of the colorblind gene. Therefore, the chance that the new baby girl will be colorblind is 25%.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.
Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemoglobin. One form of hemoglobin is 0.324% Fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of this form of hemoglobin. Make sure to include units of g/mol. Enter your answer in Scientific notation with three significant figures. The Scientific notation for 2 x 10-4 would be written as 2E-4.
Answer:
The correct answer is - 6.8950.61 gm per mole
Explanation:
Given:
One form of hemoglobin is 0.324% Fe by mass
1 hemoglobin = 4 Fe
Solution:
Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324
= 68950.61 gm
MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly below the DNA strand (remember to substitute Us for Ts in RNA) 2. Use the codon table posted below (or the circular one on the first page) to determine which amino acids are assembled to make the insulin protein in both the cow and the human. Human DNA DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA RNA GGU GLY Amino acid Cow DNA DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC RNA Amino acid
Answer:
Please find the complete table attached as an image
Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.
The table has been completed and attached below. Note that in the amino acids row;
GLY means Glycine
ILE means Isoleucine
VAL means Valine
GLN means Glutamine
CYS means Cysteine
THR means Threonine
SER means Serine
PHE means Phenylalanine
ALA means Alanine
LEU means Leucine

Explain why siblings may share similarities but are not identical.
Answer:
recombination
Explanation:
Since of recombination, kin as it were share approximately 50 percent of the same DNA, on normal. So whereas organic kin have the same family tree, their hereditary code can be distinctive in at slightest one of the zones looked at in a given test. That's genuine indeed for intimate twins.
Siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.
What is the reason behind a non-identical sibling?Siblings are not identical because each parent can contribute different variations of genes to each child, resulting in unique combinations of genetic material. Moreover, the process of meiosis, which is the formation of reproductive cells, is a random process, meaning that the chromosomes from each parent can mix in different ways during the formation of the offspring's cells. Therefore, each sibling inherits a unique combination of genetic material, leading to individual differences in physical and behavioral traits.
Hence, siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.

Why is breaking and rearranging bonds in the process of photosynthesis and cellular respiration important? WILL GIVE BRAINLIEST
Answer:
Breaking and rearranging bonds in the process of photosynthesis and cellular respiration is important because energy is released when bonds are broken in both processes. This energy is used to fuel cellular activities. Bonds are rearranged in the process of photosynthesis to make molecules of glucose; this glucose is used to fuel the process of cellular respiration, in which bonds are rearranged to form molecules of water and carbon dioxide.
In photosynthesis and cellular respiration breaking and rearranging, bonds release energy.
How is the energy released in respiration?ATP, NADH, and FADH are used to store the energy that is produced when carbon bonds are broken and rearranged in living things. Every time you exhale, carbon dioxide is expelled because cells cannot utilize it.
The extremely valuable ATP molecules are readily available to fuel cellular activity. Sugars are broken down by animal and plant cells to produce useful energy.
By severing chemical bonds and building new ones while rearranging atoms, these and other chemical processes transform materials into other compounds.
Therefore bonds release energy so breaking and rearranging bonds in the process of photosynthesis.
