Explain why the sperm cells differ from other cells in the male

Answers

sperms are gametes (reproductive cells) which have half the number of chromosomes (22 autosomes +1 sex chromosome) .Those cells have 23 chromosomes only as their nucleuse fuses *during fertilization* with the ovum's nucleuse which has 23 chromosomes as well . Also it has a special structure which makes it adapted for movement since it's a mobile cell

The connective tissue layer that surrounds an entire muscle is called ______. Multiple choice question. epimysium endomysium perimysium

Answers

Answer:

the answer is epimysium

Explanation:

The connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option as it is composed of dense, irregular connective tissue and serves to protect the muscle.

What is epimysium?

The epimysium plays a role in transmitting force from the muscle to the surrounding structures and connects to the tendons and other connective tissues that attach the muscle to bone and other structures, and the epimysium is just one of the three connective tissue layers that make up the structure of a skeletal muscle; the other two layers are the perimysium and the endomysium, and together, these three layers of connective tissue provide the necessary structural support for skeletal muscles to function properly.

Hence, the connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option.

What is the term used to describe homologous chromosomes exchanging genetic material during meiosis?.

Answers

The term used to describe homologous chromosomes exchanging genetic material during meiosis is called crossing over.

CROSSING OVER:

Crossing over is the process whereby non-sister chromatids of homologous chromosomes (similar but non-identical chromosomes from each parent) exchange genetic material.

Crossing over occurs in the prophase I stage of meiosis where homologous chromosomes lie side by side to form a structure called tetrad or bivalent.

Crossing over ensures genetic diversity in the offsprings produced meiosis.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain

Answers

The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.

A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.

These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.

Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).

In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.

Answers:

High-energy electrons from NADH and FADH2, are passed into and along the electron transport chain .

The energy from the electrons moving down the chain is used to move H+ ions across the inner membrane .

H+ ions build up in the intermembrane space, making it positively charged and making the matrix negatively charged.

In the inner membrane, H+ ions move through channels of ATP synthase .

The ATP synthase uses the energy from the moving ions to combine ADP and phosphate, forming high-energy ATP .

What differences are there in the growth of the human population compared to the animal/plant population?

Answer:

Explanation:

In both plants and animals, there are parts of the body designed to carry the nutrients needed for growth. In a animal it is blood and in a plant, it is the Xylem and Phloem Tissue Humans are born with a set number of limbs and if one get's cut off it cannot regenerate. Because of this, we are increasingly cutting into resources that other species must use in order to survive. We have hindered, or even ended the lives, of numerous species. Today, 99% of the species still remaining on this planet are at risk because of human activity alone.The similarities in the population growth of humans with respect to plants and animals is that, in the three cases, the growth occurs exponentially with respect to the initial number of specimens

Recall what you know about hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens
to the cell?

Answers

Hypotonic solutions are lowly concentrated solutions
Hypertonic are highly concentrated solutions
While isotonic have equally concentrated

When a cell is placed in a hypotonic sol water moves out of the cell by osmosis making the cell flaccid

When a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

What is osmosis?

A semi-permeable membrane is used in the process of osmosis, which allows solvent molecules to move from a solution of low concentration to a solution of high concentration.

Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.

Any solvent, including gases and supercritical liquids, can go through the osmosis process.

When solute concentrations inside and outside of the cell are equal, an isotonic solution has been created.When the concentration of solutes outside the cell is higher than within, the solution is said to be hypertonic. When the concentration of solutes inside the cell is higher than outside, the solution is said to be hypotonic.

Therefore, when a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

Hope it helped

please mark as brainliest

In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.

The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.

Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.
