What type of transport was shown in the second animation?
A. active transport with the help of transport proteins
B. passive transport by simple diffusion across the membrane
C. passive transport by facilitated diffusion with the help of transport proteins
Answer:
C. passive transport by facilitated diffusion with the help of transport proteins
Explanation:
The electron transport chain (shown in the second animation) establishes a proton gradient across the inner mitochondrial membrane. ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.
Answer:
C. passive by facilitated diffusion with the help of transport proteins
Explanation:
Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes.
Many plants that grow on land store energy in the form of starch. When the plants need energy, the molecules of starch can be broken down into monosaccharides. What type of biomolecule is starch?.
Starch is a polysaccharide biomolecule.
What are Biomolecules?Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms.

. where is the apical impulse located?
The apical impulse, also known as the point of maximal impulse (PMI), is located on the anterior chest wall where the apex of the heart touches the chest.
More specifically, the apical impulse is usually felt or seen at the fifth intercostal space in the mid-clavicular line, which is a horizontal line that runs through the middle of the clavicle (collarbone). The apical impulse is typically felt as a slight outward movement or a tapping sensation during each heartbeat. It can be used to assess the size, position, and function of the heart.
The apical impulse, also known as the point of maximal impulse (PMI), is a small but perceptible pulsation that can be felt on the chest wall over the apex of the heart, usually in the fifth intercostal space at the midclavicular line. It is caused by the left ventricle contracting and pushing the apex of the heart against the chest wall.
The apical impulse can provide important information about the size and position of the heart and the functioning of the left ventricle. It can be affected by various factors, such as age, body size, and cardiac conditions, and its location and strength can be assessed by a healthcare provider during a physical examination.

how does each of your mutations affect the amino acid sequences? Are the mutations missense mutations, silent mutations or nonsense mutations?
a. Point mutation?
b. Frameshift-insertion?
c. Frameshift-deletion?
Answer:
the correct answer is B Frame shift insertion
Explanation:
plz give me brainiest
Frameshift-insertion mutations affect the amino acid sequences.
Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.
This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.
These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.
Thus, Frameshift-insertion mutations affect the amino acid sequences.

a scientist is evaluating the hemoglobin in mountain goats compared to the hemoglobin in normal barnyard goats. how will the hemoglobin in these two goat species compare?
Mountain goats will have hemoglobin with a greater oxygen-binding affinity compared to the hemoglobin of barnyard goats.
Hemoglobin is a protein inside coral ancestry containers that's responsible for moving oxygen during the whole of vertebrates' parties. It lifts oxygen in the lungs and transfers it by way of ancestry bowls.
Mountain goats tend to live at taller altitudes. That form their red body fluid to has better oxygen-binding closeness, presumably to assure the material against fabric hypoxia (depressed oxygen level in carcass tissues) since the air in greater altitudes is finer. Mountain goats have thinner, easier skulls than real goats. Also, their horns, which are from keratin protein, are a different shape. Curving marginally back toward their heads, peak buck horns evolve shorter, thinner, and pointier than those of real goats.

Compared to barnyard goat hemoglobin, mountain goat hemoglobin will have a higher affinity for binding oxygen.
A protein found in coral ancestral tissues called hemoglobin is in charge of transporting oxygen throughout the whole life cycle of vertebrates. It transports the oxygen from the lungs to the ancestral bowls.
Mountain goats typically inhabit higher elevations. Because the air at higher altitudes is finer, they develop their red body fluid to have better oxygen-binding proximity, apparently to protect the material against fabric hypoxia. Compared to actual goats, mountain goats have easier, thinner skulls. Additionally, the curvature of their horns, which are made of keratin protein, is distinct. Peak bucks develop horns that are shorter, thinner, and pointier than those of actual goats, curving slightly back toward their heads.

How many bases are in one codon? Where do you find the codons?
Answer:
A codon is a triplet consisting of group of three bases found in mRNA sequence which eventually codes for amino acids and finally proteins.
Explanation:
A codon is a sequence of three nucleotides (bases) in a messenger RNA (mRNA) molecule that encodes for a specific amino acid or a stop signal during protein synthesis. Therefore, each codon is made up of three bases.
The sequence of bases in a codon determines the amino acid that will be added to the growing protein chain during translation.
For example, the codon AUG codes for the amino acid methionine, while the codon UGG codes for the amino acid tryptophan.
Codons are found in the coding sequence of an mRNA molecule, which is transcribed from the DNA template during gene expression.
The ribosome reads the mRNA codons during translation and matches each codon with a specific amino acid or a stop signal, thereby synthesizing a protein.
The genetic code, which maps each codon to a specific amino acid or a stop signal, is universal across all known organisms.

The true statement about sister chromatid is: (b) they are tightly connected at the centromere.
Chromatid is the part of the chromosome that has a long thread-like appearance. there are two chromatids in one chromosome and they are denoted as sister chromatids. Each chromatid is the house for certain genes.
Centromere is the region of the chromosome where the two sister chromatids attach together. These are the constructed regions of the chromosome. Centromere is also the region for the attachment of spindle fibers during the process of cell division. Spindle fibers do not attach directly to the centromere instead attach via a protein called kinetochore.

If a child has blood type ------------ when his mother has blood type a, o for his father?
If a child has blood type O when his mother has blood type A and his father has blood type O, it is possible but less likely, as the child would have inherited the O allele from both parents.
Blood type inheritance follows specific patterns based on the ABO system. Each person inherits two alleles for blood type, one from each parent. The A allele and the B allele are dominant, while the O allele is recessive. In this case, the mother has blood type A, which means she could have two possible genotypes: AO (heterozygous) or AA (homozygous).
The father has blood type O, which means he has the genotype OO (homozygous). Since the O allele is recessive, the child can only have blood type O if they inherit the O allele from both parents.
If the mother is heterozygous (AO) and the father is homozygous for O (OO), there is a 50% chance of the child inheriting an O allele from the mother and a 100% chance of inheriting an O allele from the father. Thus, the child has a 50% chance of having blood type O.
However, if the mother is homozygous for A (AA) and the father is homozygous for O (OO), it is impossible for the child to have blood type O, as the child would definitely inherit an A allele from the mother.
