19. What do you expect when the cell wall of a plant cell is removed by a certain way, then put in distilled water? a)The cell takes a longer time to swell. b)The proteins that are present in the cytoplasm exit through the cell membrane. c) The cell shrinks. d) The cell bursts. why is the correct answer (d)
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..
How do plant cells react to exposure to distilled water?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

Describe in your own words the process of gene expression (DNA → RNA → proteins)
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.
What is gene expression?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.

Explain why the energy available at the top layer of the pyramid is a small percentage of the energy present at the bottom of the pyramid: *
The energy available at the top of the pyramid is a small percentage of the energy present at the bottom of the pyramid because of the process of energy transfer.
As energy flows up the pyramid, each level of the pyramid takes in energy from the level below and uses it to produce its own energy. This energy transfer is not 100% efficient, so some energy is lost at each level. By the time the energy reaches the top of the pyramid, the amount of available energy is greatly reduced.
Additionally, the organisms at the top of the pyramid have to use energy to stay alive and move around, so there is even less energy left to transfer to the next level. This is why the energy available at the top of the pyramid is so much smaller than the energy present at the bottom.

According to the primitive earth model which one of the following compounds was not present in the beginning.
A.NH3
B.H2S
C.CO2
D.O2
The Correct answer is Option D.Oxygen
According to Oparin, oxygen was not present in the primitive atmosphere of the Earth.
What is Oxygen?The chemical element with the atomic number 8 and symbol O is called oxygen. It belongs to the periodic table's chalcogen group, is a very reactive nonmetal, and an oxidising agent that easily produces oxides with most elements as well as other compounds. After hydrogen and helium, oxygen is the third most plentiful element in the universe and the most abundant element on Earth. Two atoms of the element combine to generate dioxygen, an odourless and colourless diatomic gas with the formula O 2 at standard pressure and temperature.
According to researchers at MIT, the Great Oxygenation Event (GOE), which is thought to have started as early as 2.33 billion years ago, was the beginning of oxygen's ongoing presence in the atmosphere.
Oxygen in Primitive EarthLouis Pasteur wrote about his research in 1864, demonstrating that microbial life could not have developed spontaneously in the absence of preceding life. This work is regarded as a milestone in modern science as it resolved a long-running debate regarding spontaneous generation.
The concept of spontaneous genesis holds that live things could appear miraculously from inanimate matter.
But Pasteur's findings presented evolutionary biologists with a fresh conundrum: if life could only develop from life, how did living things first originate on the planet?
The solution was presented in the 1920s by A.I. Oparin of Russia and J.B.S. Haldane of England, who independently made compelling cases that the origin of life could be explained by a lengthy and gradual process of chemical evolution rather than by the rapid spontaneous generation of complete organisms in a matter of weeks.
Elements primitive earthAn atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulphide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there.

Group of answer choices interact strongly with the molecules they transport undergo a conformation change with every solute they transport can only mediate passive transport form pores that are always open are always controlled by voltage
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.

Which substances are neuropeptides that inhibit pain impulse transmission in the brain and spinal cord
The most important of them is beta-endorphin, which, in addition to significantly lowering pain (its analgesic potency is many times that of morphine), is the opioid peptide that induces the most pleasure.
GABA, a neurotransmitter, also plays a role in central pain regulation by enhancing descending inhibition of spinal nociceptive neurons.
Neuropeptides are a broad category of chemically unique compounds that are found in and emitted by various sensory neurons. They play a role in the development, transmission, modulation, and perception of all forms of pain (physiological, neuropathic and inflammatory).
