Explain how a root hair cell is specialised for its function

The cell bursts when the cell wall of a plant cell is removed by a certain way, then put in distilled water because the cell wall is removed, the cell would get wet, which would cause it to burst..

Putting a plant cell in distilled water causes it to become turgid. This is due to a process called osmosis, which causes the plant cell's cytoplasm to swell up and firmly press up against the cell wall as it absorbs water from the hypotonic distilled water.

Cell walls stop excessive endosmosis from happening when water enters the cell, which also prevents plant cells from bursting. If the cell wall were to be broken, water would enter the space and the cell would eventually burst.

During sexual reproduction, two gametes (sex cells) fuse to create a fertilized cell (zygote) with a complete set of chromosomes. What must be true about the number of chromosomes in each gamete is only one set of chromosomes.

Sexual reproduction is a way of developing living things by combining genetic information from two individuals of different sexes through the process of fertilization. Fertilization occurs when an egg and sperm cell meet to produce a zygote.

Chromosomes are a group of fine threads in cells that function as carriers and stores of genetic information in living things. Gamete cells have one set of chromosomes (haploid) consisting of 23 chromosomes with the composition of sperm cells 22 A + X or 22 A + Y and ovum cells: 22 A + X

Answer:  A. DNA is transcribed into RNA, which is translated into protein

Explanation:

The process of gene expression is the information from DNA is transcribed into RNA, then this RNA is translated into protein.

Gene expression is the process of directing protein synthesis by utilizing the genetic information encoded in genes (DNA). Gene expression enables organisms to develop various cell types and adapt to internal and external influences.

The process of gene excretion takes place in the cell nucleus and cytoplasm and is divided into two stages: transcription and translation.

DNA is employed in the transcription process to create copies in the form of mRNA. While translation is the process by which individual polypeptides are synthesized in the ribosome. Protein can be made up of one or more polypeptides.

Therefore, the information from DNA is transcribed into RNA, which is then translated into protein during the gene expression process.

In contrast to transporters, ion channels in cellular membranes can only mediate passive transport form pores.

Only in order to open a membrane pore that enables a certain ion into the membrane do channel proteins undergo a conformation in the membrane. In contrast to carrier proteins, the ion will only move along its concentration gradient. It has been discovered that all membrane transport proteins that have been in-depth study are multipass transmembrane proteins, meaning that their transporters chains repeatedly pass through the lipid bilayer.  These proteins allow certain hydrophilic solutes to traverse the membrane without coming into touch with the hydrophobic interior of the lipid bilayer by establishing a continuous protein pathway across the membrane.

A diploid individual cell with a chromosome number of 32 contains two haploid sets of chromosomes. A haploid set of chromosomes is a complete set of chromosomes that contains one of each type of chromosome.

Each haploid set contains 16 chromosomes in the diploid individual cell with a chromosome number of 32. During the process of meiosis, the parent cell divides into four daughter cells. During this process, the two haploid sets of chromosomes that were present in the parent cell are separated into the four daughter cells.

During the formation of the four daughter cells, each daughter cell contains only one haploid set of chromosomes. This means that in a diploid individual cell with a chromosome number of 32, there are two haploid sets of chromosomes present.

The two haploid sets of chromosomes present in a diploid individual cell with a chromosome number of 32 each contain 16 different chromosomes. These chromosomes are responsible for the genetic traits of the individual. Each of the 16 chromosomes contains specific genes that control certain traits. These genes are responsible for the physical characteristics of the individual, such as hair color, eye color, and height. These chromosomes also contain information that determines the sex of the individual.

Lactate production increase when the energy (ATP) needed is high but oxygen levels are low. To fulfill this demand, the rate of lactic acid metabolism must be increased as well.

Lactate as waste is the product of fermentation or anaerobic respiration. Anaerobic respiration is categorized into alcoholic metabolism and lactic acid metabolism.

Lactic acid metabolism itself is the metabolic process that produces a little energy. In this metabolism, besides yield 2 ATP also produces lactate per glucose. The process happens in muscle cells as not being supplied with enough oxygen. Times when our body's oxygen level might drop is during intense exercise, whereas, at this condition the demand for ATP is increased.

Dideoxynucleotides triphosphates are referred to as ddNTP. Four kinds of nucleotides are included in it: ddATP, ddTTP, ddCTP, and ddGTP. Sanger sequencing, also known as chain-termination sequencing, employs ddNTP.

This ddNTP lacks a free hydroxyl (OH) group necessary for DNA replication, it is employed to prevent DNA synthesis. They are also known as 2' 3' because they lack hydroxyl groups on the ribose at either the 2' or 3' locations. As a result, they stop the chain from elongating because no phosphodiester bond is formed with the subsequent carbon.

2. It is converted into heat and energy.

Explanation:

So every time an animal eats grass, or another animal it receives 10% of the energy that the previous animal/plant had. If a rabbit ate a carrot, 10 percent of the energy the carrot had in it, will go into the rabbit. the question is asking where the 90% energy from the eaten carrot went.

Answer Explanation:

Most of the energy that isn't stored in the animal/plant is lost as heat or is used up by the body as it digests the animal/plant that was eaten. This is because the animals who consume any of the plants/animals receiving the 10% energy take energy to eat the plant/animal. this takes up the other 90%
