The answer is ligand gated channels.
Ligand gated channels are also called as ionotropic receptors that open in response to the binding of specific ion, which is generally not solute. These are made up of particular set of transmembrane proteins that open and close to allow the movement of ions like K+, Na+ that passes through the plasma membrane in response to binding of the chemical messenger.
A channel that opens due to a specific patch list but doesn't inescapably transport that patch is known as aligand-gated channel, playing a vital part in whim-whams signal transmission.
A channel that opens in response to the list of a specific patch, which is generally not the solute that passes through the channel, is called aligand-gated channel. These channels are a type of ionotropic receptor because when the ligand, frequently a neurotransmitter in the nervous system, binds to the protein, ions can cross the membrane changing its charge. Ligand-gated ion channels are pivotal for the rapid-fire transmission of signals across the synaptic gap between neurons.

The traits studied in the experiments involving the crossing of pea plants are seed shape and seed color.
-The shape of the seeds can either be round or wrinkled, and the alleles of these traits are represented by R and r respectively. Allele R is dominant.
-The color of the seeds can be yellow(Y) or green (y). The allele for the yellow seeds is dominant.
A dihybrid cross is preformed between the two pea plants of genotype RrYy. Construct the Punnett square for the corss in the table shown.
QUESTION: Explain how the Punnett square can be used to predict the probability that an offspring from such a cross has a given phenotype (for example yellow, wrinkled seed) Explain your answer with reference to Mendel's Law of independent Assortment.
Hi,
As mentioned in the question, R is for round seeds which is a dominant trait over wrinkled seed r.
Similarly, Yellow color of seeds Y is a dominant trait which is dominant over green color of seeds y.
A dihybrid cross is preformed between the two pea plants of genotype RrYy.
P1: RrYy X RrYy
Gametes: RY: Ry: rY: ry
Offspring: Given in punnet square
So, we have the question: how the Punnett square can be used to predict the probability that an offspring from such a cross has a given phenotype .
The answer lies in the fact that we know which allele is for dominant trait and which allele is for recessive trait. So when we look at any genotype of offspring for example: RRYY, we know it will have round seed and yellow color because it has both alleles of dominant nature. Similarly, if we talk about offspring RrYY we see that it will also have round seed and yellow color because although allele for green color is present but its effect is masked by dominant allele R. In this way we can predict the phenotype of all the offspring.
1 RRYY: Round and green
2 RRYy: Round and green
1 RRyy: Round and green
2: RrYY: Round and yellow
4: RrYy: Round and yellow
2: Rryy: Round and green
1: rrYY: wrinkled and yellow
2: rrYy: wrinkled and yellow
1: rryy: wrinkled and green
So it means that out of 16 offspring:
6 will have Round and green phenotype.
6 will have phenotype round and yellow
3 will have phenotype wrinkled and yellow
1 will have phenotype wrinkled and green
Therefore, we can calculate the probability of offspring by seeing punnet square and if we know the dominant or recessive nature of allele.

At least half of the world’s species of land organisms live in a..
a) tropical rain forest.
b) temperate savanna.
c) temperate forest.
d) tropical desert.
A) Tropical rain forest.
This is one of the myriad reasons that it is vital that we protect and preserve our rain forests.
Answer:
(A)- Tropical moist forests
Explanation:
Rainforests have high biodiversity because they are abundant in nutrients, energy and a favourable climate. Tropical rainforests have warm temperatures and lots of precipitation. The high-intensity sunlight provides energy for producers in the rainforest and supports a wide variety of plant growth.
Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.

Describe a plant organism who went through asexual reproduction (with spores) and how it grows up. Make sure it is in 1st person PoV
Reproduction in plants can be by vegetative propagation, through the vegetative propagules like the rhizomes or tubers, asexual reproduction by the production of spores and sexual reproduction by the formation of the male and female gametes.
Spores are the agents of asexual reproduction in plants. They are formed in the non-seed-bearing plants like the liverworts, hornworts, mosses and ferns. The ferns are the group of vascular plants that reproduce by spores. The leaves of the ferns (fronds) contain numerous sporangia which produce tiny spores. When the sporangia breaks open, the spores are released and dispersed by the wind. On encountering favourable conditions of the environment, these spores grow into tiny plants called the gametophytes.

If a pea plant that is herterozygous for rounds, yellow peas is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas, how many different phenotypes are their offspring expected to show?
Final answer:
When crossing a heterozygous round, yellow pea plant with a homozygous round but heterozygous yellow pea plant, we would expect two different phenotypes: round yellow and round green peas.
Explanation:
The student asked to determine the phenotypes of offspring when a pea plant heterozygous for round, yellow peas is crossed with a pea plant homozygous for round peas but heterozygous for yellow peas. The genotypes for round peas are given as R (dominant) and r (recessive), and for yellow peas as Y (dominant) and y (recessive). Therefore, the parental genotypes will be RrYy (heterozygous for both traits) and RrYY (homozygous for round and heterozygous for yellow).
To find the number of different phenotypes, you would conduct a Punnett square analysis. The possible combinations of these alleles would show the expected offspring's genotypes. Genotypically, we expect to see 1/2 of the offspring being R-Y- (either RrYy or RRYy, both resulting in round yellow peas since the R and Y alleles are dominant) and the other 1/2 being RrYY. This cross would therefore produce two different phenotypes: round yellow peas and round green peas if any recessive alleles come into play.
"The offspring of this cross are expected to show two different phenotypes.
To determine the number of different phenotypes expected in the offspring, we need to consider the genotypes of the parent plants and use the principles of Mendelian genetics.
The first parent plant is heterozygous for both round peas (Rr) and yellow peas (Yy). The second parent plant is homozygous for round peas (RR) but heterozygous for yellow peas (Yy).
The cross can be represented as follows:
RrYy (first parent) x RRYy (second parent)
When we perform a dihybrid cross, we can look at each trait separately:
For the shape trait (round vs. wrinkled):
- The first parent contributes either R or r with equal probability.
- The second parent contributes R (since it is homozygous RR).
For the color trait (yellow vs. green):
- The first parent contributes either Y or y with equal probability.
- The second parent contributes either Y or y with equal probability (since it is heterozygous Yy).
Now, let's look at the possible gametes for each trait:
- Shape: R and r (from the first parent), R (from the second parent).
- Color: Y and y (from both parents).
The possible combinations of gametes for the offspring are:
- RY, Ry, rY, ry
Since the second parent is homozygous for the round trait (RR), all offspring will inherit the R allele for round shape from this parent. Therefore, the shape of the peas in the offspring will be round regardless of the allele received from the first parent.
For the color trait, since both parents can contribute either Y or y, the offspring can have the following genotypes: YY, Yy, or yy. However, because the yellow color (Y) is dominant over green (y), the YY and Yy genotypes will result in yellow peas, while only the yy genotypes will result in green peas.
Therefore, the offspring will show two different phenotypes:
1. Round, yellow peas (from R_Y_ or R_Yy genotypes)
2. Round, green peas (from R_yy genotypes)
In summary, the offspring will exhibit two phenotypes: round, yellow peas and round, green peas."

3. What pattern do you notice in the genotypes of the F1 generation snapdragons?
Answer:
In snapdragon plants, phenomenon of incomplete dominance is observed.
Incomplete dominance is a type of inheritance in which the dominant allele can not express itself completely over the recessive allele.
It leads to the generation of intermediate phenotype in heterozygous condition.
Due to this reason, when two purebred snapdragon plants form red and white flowers are crossed, it results in the production of offspring all with pink flower that is, an intermediate phenotype of red and white.

Describe the process of DNA replication. Name the enzymes involved and state their functions.
Final answer:
DNA replication is the process by which a cell makes an exact copy of its DNA. It involves enzymes such as DNA Helicase, DNA Polymerase, and DNA Ligase.
Explanation:
DNA replication is the process by which a cell makes an exact copy of its DNA. It is called a 'semi-conservative' process because each newly synthesized DNA strand contains one original strand and one newly synthesized strand.
The enzymes involved in DNA replication are:
DNA Helicase: This enzyme unwinds the DNA helix by breaking the hydrogen bonds between the base pairs.DNA Polymerase: This enzyme adds new nucleotides to the growing DNA strand, using the original DNA strand as a template.DNA Ligase: This enzyme seals the gaps between the Okazaki fragments on the lagging strand.These cells are part of he domains archaea and bacteria prokaryotes or eukaryotes
No matter what the cell type, prokaryotic or eukaryotic, plant or animal, the ____________ forms a protective barrier between the exterior environment and the interior of the cell. A) cell wall B) cytoskeleton Eliminate C) cell membrane D) glycoproteins
Answer: C). cell membrane
The cell membrane is the membrane that can be found in both eukaryotic and prokaryotic cells. It is the cell that separates the interior of the cell from the extracellular environment. It is a protective layer that allows only the selected ions and organic molecules to enter inside the cells and go out of the cell, hence is called as selectively permeable or semi-permeable membrane. This phenomena maintains the concentration of ions and molecules inside the cell and prevents dehydration, cell rupture due to high concentration.

Briefly explain why cutting a flatworm into pieces would not kill it
Cleaving a flatworm into pieces would not kill the flatworm as each piece would turn into a new flatworm. The mechanism is known as fragmentation. In multicellular species, fragmentation refers to a kind of asexual reproduction in which a species gets cleaved into fragments.
Each of these fragments forms into completely developed, mature individuals, which are similar to their parents. Fragmentation is also called splitting, it is a mode of reproduction witnessed in various species like molds, filamentous cyanobacteria, lichens, various plants, and animals like flatworms, sponges, sea stars, and some annelids.
A flatworm wouldn't die when cut into pieces due to their ability for regeneration where they can grow back severed parts, a simple body structure that lacks major internal organs, and physiological processes that rely on diffusion and cell-to-cell junctions for nutrient and gas exchange.
Explanation:Cutting a flatworm into pieces would not kill it because of its remarkable ability for regeneration. This means that if an individual is severed, it can regrow its head or tail, or even several heads if the planaria is cut lengthwise. Additionally, flatworms are capable of asexual reproduction where an entire organism can be regenerated from just part of it.
Another reason as to why a flatworm wouldn't die when cut into pieces is its physiological processes. Flatworms have an incomplete digestive system with an opening, known as the 'mouth', that is also used to expel digestive waste. This means they do not dependent on major internal organs to process their food. Furthermore, they do not have circulatory or respiratory systems, with gas and nutrient exchange dependent on diffusion and cell-to-cell junctions.
Lastly, flatworms have a simple body structure that doesn't contain any internal body cavities. Their bodies consist of three layers that give rise to various tissues, and the materials needed by the flatworm can easily diffuse through their bodies. So, no major organ would be lost if the flatworm is cut, and each piece can eventually grow into a new flatworm.
