Answer:
The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.
The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.
The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.
On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.

The one–toed horse of today steadily evolved from its five–toed ancestor. Which theory of evolution can explain this example?
Answer:
Horses have genes of having five toes, but as they grow, the other four don't develop. This is an example of patterning and post-patterning modes of evolution. Horses don't hunt preys, so they don't need claws. Horses develops muscles and "the hoof" for them to cover wide areas and long distances.
Explanation:
This is the correct answer.

A cell can form beads on a string chromatin, but not solenoid fibers. Which molecule has likely been removed or mutated in this cell?
a. Η1
b. non-histone proteins
c. H2A
d. topoisomerase
The molecule which has likely been removed or mutated from a cell that can form beads on a string chromatin, but not solenoid fibers is: A. Η1
A cell can be defined as the fundamental functional, structural and smallest unit of life for all living organisms.
Genome editing refers to a high-tech process through which scientists remove (delete), replace or insert a deoxyribonucleic acid (DNA) sequence into the cells of a living organism such as an animal, bacterium, plant, etc., so as to improve on its physical and chemical conditions or correct a genetic disorder.
Chromatin can be defined as a complex form of deoxyribonucleic acid (DNA) and protein found in the cells of an eukaryotic organism.
In the classic model of chromatin, the beads simply refer to the nucleosomes while the string is simply the linker deoxyribonucleic acid (DNA).
Basically, the deoxyribonucleic acid (DNA) is wrapped around histone proteins to form nucleosomes and the beads on a string structure (euchromatin).
Furthermore, there exists a linker histone H1 in addition to core histones that reaches the entry or exit of the deoxyribonucleic acid (DNA) strand on the nucleosome.
In conclusion, a cell cannot form beads on solenoid fibers but it can form beads on a string chromatin because the H1 molecule has likely been removed or mutated in the cell.

explain how the difference in diameter is responsible for the process that occurs in the malpighian body
Answer:
Explanation:
Malpighian body is made up of the glomerulus and the Bowman's Capsule. The glomerulus is a network of capillaries that receives blood from the afferent arteriole and gives it further to the efferent arteriole. From the glomerulus, the component of blood diffuse into the Bowman's Capsule through the endothelium and basement membrane of the glomerulus and the epithelium of Bowman's Capsule.
The blood comes into the glomerulus through which it is diffused into the Bowman's capsule. Only the smaller solute molecules and water is allowed to pass through the membranes while the blood cells are retained within the glomerulus. Hence, the Malpighian Body allows the filtration of blood so that the waste can be separated from the blood. The filtrate further moves to tubules where fine reabsorption and secretion takes place. Both the kidneys produce approximately 180 liters of filtrate every day.
The difference in diameter is responsible for the process that occurs in the malpighian body as - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.
Malpighian Body is a structure located in Nephron in the urinary system that helps in ultrafiltration of blood. It consists of a glomerulus and its surrounding Bowman's capsule.
There are two main arteries in the Malpighian body of blood vessels
one entered for filtration, called afferent arteriole.one leaving the structure after filtration called efferent arteriole.Differences in diameter provide for the increased blood pressure in the glomerulus for ultrafiltration.The afferent arteriole has a larger diameter, which leads to more blood would flow into the efferent arteriole, which is of a smaller diameter due to this causes more blood pressure or hydrostatic pressure in the glomerulus.Thus, the correct answer is - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.

Moosehead Lake in Maine is a beautiful lake, spanning 74,890 acres with a maximum depth of 246 feet. The most sought-after fish to be found in Moosehead Lake are: Landlocked salmon, lake trout, brook trout, and burbot. According to Tim Obrey, a regional fisheries biologist with the Maine Department of Inland Fisheries and Wildlife, the fishing at Moosehead declined from phenomenal to just "really good" during the late 1980s, but has rebounded due to careful management. This table shows the populations of three major fish in Moosehead Lake over a 30 year period. Moosehead Lake was illegally stocked with smallmouth bass in 1970. Fish Populations in Moosehead Lake Year Smallmouth Bass Salmon Lake Trout
Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What would be appropriate action for Wildlife Management to make to correct the problem? Choose ALL that apply.
B) One hundred small, one-hectare size areas should be conserved
C) Native species should be maintained or planted within the greenspace to promote biodiversity.
D) Exotic species should be cultivated and planted to increase biodiversity in the protected greenspace.
E) The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
(WILL GIVE BRAINLIEST WHOEVER CAN ANSWER RIGHT!!!!!!)
When one of the trophic web links disappears, it affects the whole chain. In management programs it is important to consider these consequences to keep the whole ecosystem equilibrium. In the exposed situation, Native species should be maintained or planted within the greenspace to promote biodiversity and The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
--------------------------------------
The trophic chain is the energy transference process that involves different organisms, from autotroph or producers, to the consumers or decomposers.
The disappearance of one link affects the whole system. The direct superior link does not have enough food supply, while the immediately anterior link is beneficiated for not being eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link. Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem.
It is necessary and significant to consider these modifications in the whole ecosystem while planning management actions to keep an equilibrium.
In the exposed example we know that the most wanted species are
Landlocked salmon, lake trout → which increased its population size sharply over the last yearsbrook trout, and burbotSmelts, which are the primary food source for lake trout and salmon, decreased in population size significantly.
Finally we know that smallmouth bass was introduced in 1970.
This information suggests that the decrease in smelts' population is due to the predation of the species by the lake trout, which population increased sharply in size. The change on smelts' population size, might affect the blook trout and salmon populations, that also feed on semelts, and might also affect other species occupying inferior levels.
When implementing a management program, it would be necessary to promote biodiversity by growing native species in greenspaces and ensure their survival and reproductive succes. In the exposed case, it is necessary to preserve smelts' population, so it would be also necessary to remove from these green spaces the secondary consumers -trouts and salmon- that feed on them, to ensure the smelts' population growth and recovery.

Zhengzhou, the capital city of Henan province, was hit by heavy rain at 4 PM July 20. By 17 o'clock, rainfall per hour reached 201.9 mm, which has exceeded the extreme value of China's hourly rainfall capacity on land, resulting in poor drainage, severe waterlogged, economic losses, and enormous casualties. However, with the strong support of the Chinese government and all parts of the country, the people of Zhengzhou united as one to actively carry out self-rescue operations, relief, and rescue work. All these have achieved initial success. Guo Wengui, who is far away in New York, has been working in Zhengzhou for many years, and Yuda Building is just in Zhengzhou. He should have felt empathy for the heavy rain in Zhengzhou. But surprisingly, He turned a happy face to this. At the same time, Cheater Guo tried to describe natural disasters as human-made ones and encourage Guo investors to donate to Zhengzhou. There must be some triggers in this donation because of the duplicity and the inconsistency. Comrades, keep your eyes open! Don't be fooled!

B) two more clectrons than carbon-12.
C) two more neutrons than carbon-12.
D) A and C only
E) B and C only
Answer:
C
Explanation:
this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.
further more explanation:
it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!
for carbon 12= 12-6=6
for for carbon 14=14-6=8 which means the best alternative is Choice C.

Timber is the one that describes the ecosystem services. The correct option is 2.
What is ecosystem services?Many of the basic offerings that people rely on are provided by ecosystems. Plants purify the air and water, bacteria biodegrade waste, bees pollinate flowers, and tree roots keep soil in place to safeguard against erosion.
These are fairly simple to identify. Food, water, timber, fibers, and even medicine are among them. Other naturalistic explanations and materials are controlled by regulating services.
Goods such as food and water are illustrations of ecosystem services, as are the regulation of floods, soil erosion, and disease outbreaks, as well as non-material benefits such as recreational and religious benefits in natural areas.
