1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. 3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.
Answers
Answer:
1- Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.
2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.
3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.
Why is it important for cells of multicellular organisms to undergo mitosis? A) mitosis allows for reproduction B)mitosis increases variation within an organism. C) mitosis produces cells that are different from the original dividing cell. D)mitosis produces cells that are identical to the original diving cell
Answers
The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.
Hope this helps ! <3
It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.
Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.
The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.
Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.

c) Assume that the concentration of the solute molecules varies over time on both sides of the membrane and that the solute molecules continue to pass through the membrane even when the concentration gradient is the reverse of the gradient shown. Describe the environment in and around the cell, as shown in the diagram, and the mechanism of transport of the solute molecules. (3 points)
Answers
Answer:
Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?
The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.
The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.
The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.
The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

An active site contains a binding site that binds the substrate and orients it for

Explanation:
Each monomer is correctly connected to its polymer in the attached image in which amino acid is attached with protein, the nucleotide is connected to DNA, the fatty acid is attached to fat or lipid, and glucose or sugar is attached to carbohydrates.
Monomers are the basic unit or building blocks of larger molecules known as polymers. Polymers are made up of two or more monomers or long chains of monomers attached together.
The macromolecules are polymers and made up of their particular monomers:
Proteins made up of amino acids: In the protein structure there are many amino acids are joined together with help of peptide bonds and due to this, it is also called a polypeptide chain.Nucleic acid (DNA) is made up of nucleotides- nucleotide monomers bind together and form chains of the nucleotides.Fat made up of fatty acids: Fats or lipids are polymers made up of long chains of fatty acids,carbohydrates made up of glucose monomers: glucose or other monosaccharides bind together to form polysaccharides or carbohydrates.Thus, the correct answer is attached as the image.

Answers
Answer:
Ichthyosaurs lived from Triassic to Middle Cretaceous approximately 250 million years ago until 110 million years ago
Explanation:
Ichthyosaurs evolved during the early Triassic period from land reptiles. This group was characterized by a spindle-shaped body, a shoulder girdle connected to a streamlined skull, two pairs of limbs, and digit-like bones. Moreover, Ichthyosaurs drew oxygen from the atmosphere (i.e., like marine mammals). Utatsusaurus is the oldest known Ichthyosaur species and it lived during the Lower Triassic. ln the same way to the land reptiles, Utatsusaurus had a pelvic girdle attached to the spine, and an equal length between the humerus and femur.

Answer:

Explanation:

The molecules supply the main source of short-term energy used in cellular respiration is - G) carbohydrates.
All living organisms carry out cellular respiration in order to get energy for cellular processes. All biomolecules proteins, lipids, and carbohydrates provide energy by breaking down during this process. however, sugar molecules or carbohydrates are used to provide short-term and immediate energy in the form of ATP by cellular respiration.
Proteins -
During extreme starvation when all carbohydrates and fats in the body are used up.The respiratory quotient (RQ) of proteins - 0.83–0.9.Carbohydrates-
The major respiratory substrate is in form of glucose or carbohydrates in cells.The respiratory quotient (RQ) of carbohydrates - 1.Fats-
used only if carbohydrates are in short supply. It yields almost twice as much energy as carbohydrates generally do not use.The respiratory quotient (RQ) - 0.71Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.
