what adaptations have allowed tetrapods to survive on land
Answer:
It is extremely useful for terrestrial organisms because it allows them to use their hindlimbs efficiently for locomotion on land. Since the aquatic ancestors of fishes and tetrapods had no such connection, one might guess that this feature first evolved serving the function of enabling terrestrial locomotion.
Answer: When the land animals began to use the fins for standing and walking, the girdle bones had to become stronger to support the body on the legs. These bones eventually became the femur (upper leg bone) and humerus (upper arm bone) of the tetrapods
If the pride is taken over by new individuals, what happens to the females? males? cubs?.
The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.
Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.Learn more about pride here:

If a DNA strand has 32 % guanine before semi conservative replication occurs, what
percent thymine will each new strand have after replication?
Answer:I believe that the answer would be 18
Explanation:
32 divided by 2 is 18
If a DNA strand has 32% Guanine before semi-conservative replication occurs, then the percent Thymine will each new strand have after replication will be 18%.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of four types of nucleotides: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).In DNA, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G). The replication of DNA is semi-conservative because after replication each DNA molecule contains one original DNA strand and one newly-synthesized DNA strand.If a DNA molecule contains 32% of Guanine, then the content of G + C is equal to 64%, so the content of T + A is equal to 36% (64 + 36 = 100) and T content is 18% (18 + 18 = 36).In conclusion, if a DNA strand has 32% of Guanine before replication, then the percent of Thymine after replication will be 18%.

Solution that has a higher solute concentration on one side of a membrane than the other side.
A solution that has a higher solute concentration on one side of a membrane than the other side is termed as a hypertonic solution.
The cell membrane is a semi-permeable membrane that allows selective entry of materials into and out of a cell. Due to this, a concentration gradient develops inside and outside of the cell.
Such a solution that has more solutes present is referred to as a hypertonic solution. As a result of the hypertonic solution, a concentration gradient will be developed. Of a hypertonic solution is present inside the cell, then water from outside will enter the cell. On the other hand, if a hypertonic solution is present outside the cell, then water from inside the cell will move outwards.

The diagram below shows a phospholipid molecule.
Which of the following best describes how this molecule is produced by eukaryotic cells?
Question 12 options:
The nucleus sends out mRNA to the smooth ER (endoplasmic reticulum) so it can assemble the phospholipids using amino acids that are transported into the cell by the cell membrane. Vacuoles carry glucose to the smooth ER to supply the energy.
The enzymes needed to assemble it are from the Golgi. The smooth ER (endoplasmic reticulum) assembles the phospholipids using fatty acid tails that are transported into the cell through the cell membrane. Energy for the reaction comes from the mitochondria as ATP.
The enzymes needed to assemble it are from ribosomes. The rough ER (endoplasmic reticulum) assembles the phospholipids using energy from the mitochondria. The cell membrane transports new amino acids into the cell that are changed in the phospholipid.
The nucleus sends instructions out to the smooth ER (endoplasmic reticulum) to build the phospholipid. The cell membrane transports fatty acid tails into the cell to be used, and energy for the reaction comes from the mitochondria as ATP.
The nucleus sends instructions out to the smooth ER (endoplasmic reticulum) to build the phospholipid. The cell membrane transports fatty acid tails into the cell to be used, and energy for the reaction comes from the mitochondria as ATP.

in the phase of wound healing, collagen closes the gap between tissues and scar tissue forms
In the phase of wound healing, collagen closes the gap between tissues, and scar tissue forms. This phase is called the Remodelling phase because collagen continues to increase, and the tissue begins to contract with the help of fibroblasts, which adds strength to the new tissue.
However, gradually excessive collagen in the fibrin framework can cause scar tissue formation.
Therefore, at the injury site, the fibrin in blood stops the blood flow and provides mechanical support to the collagens, a protein that helps close the gap between injured tissues and gives strength to the newly formed tissue. This phase continues for six or more months. Thus, it is called as remodel or remodelling phase.
