Answer:

1 We can infer that when permeable channels are added to the peptides and a cell is incorporated in water, the concentration of peptides and water will change, generating an equilibrium causing an equivalence of equal intracellular and extracellular concentration

2. If there is no alteration and the environment is in equilibrium, we can say that there will be an equal concentration of petids and water in the intracellular and extracellular space. If we have 40 peptides on the left side, the right side will move looking for a balance and that both environments are the same, becoming 60 for each of the spaces

Although your question has some missing details a general answer is provided above

After adding the channels to a system to achieve equilibrium the number of peptide molecules on both sides of the cell have to be equal.

A difference in the peptide molecules on either side of the cell will lead to a diffusion gradient and this will lead to diffusion of peptide molecules from the side with higher concentration of peptide molecules to the side with lower concentration of peptide molecules ( this means that the system is not at a stable state ).  while

A difference in the concentration of the water molecules will lead to an osmotic gradient  ( this means the system is not at a stable state ).

Hence we can conclude that for the system to reach a stable state the number of peptide molecules and the water molecules on both sides of the cell should be equal.

Answer:

water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion

Explanation:

water moves from roots to leaves. ... Because water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion), they rise up the tubes all the way from the roots to the leaves.

Water molecules prefer to attach together and to the sidewalls of the cellulose tubes via which water travels from roots to the leaves.

Water molecules ascend up the tubes from the roots of plants because they like to adhere together (cohesion) and attach to the walls of the cellulose tubes (adhesion).

Capillary motion is what we term when water travels into small gaps like that. Because the water particles bonded to the coloring and carried it along, the color in the water travelled up into the celery with both the water in this process. Water going into a plant in nature brings nutrients from the earth with it.

Explanation:

Thermoregulation itself is actually a branch of homeostasis. Homeostasis is defined as the internal regulation of body environment which includes the vital organs of the body such as the heart, liver, brain and contraction of skeletal muscles.

However, there are four routes of heat lost in the body. They are through convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such conditions, the only means by which the body can rid itself of heat is by evaporation. So, when the surrounding temperature is higher than the skin temperature, anything that prevents adequate evaporation will cause the internal body temperature to rise. Even during sports activities, evaporation becomes the main avenue of heat loss. Humidity itself, affects thermoregulation by limiting sweat evaporation and thus heat loss.

I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.

Explanation:

Top three concerns regarding the hydroelectric dam and the biodiversity of the region

Hydropower can also cause environmental and social problems. Reservoirs drastically change the landscape and rivers they are built on. Dams and reservoirs can reduce river flows, raise water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.

Hydroelectric plants alter the natural habitats of freshwater species in the areas they are located. It changes the concentration of nutrients, water temperature, and the river's flow. Downstream river flow suffers a loss of water and silt loads, reducing water quality.

Answer:

the population has a Hardy-Weinberg equilibrium

Explanation:

According to the case and the information given, the genotype frequencies are:

EE (p2) = 0.61

Ee (2pq) = 0.26

ee (q2) = 0.13

To obtain the allele frequencies we can perform the following equation

Frequency of E = p = p2 + 1/2 (2pq) = 0.61 + 1/2 (0.26) = 0.61+ 0.13 = 0.74

replacing the data we obtain:

Frequency of e = q = 1- p = 1 - 0.74 = 0.26

Regarding the expected frequencies of the genotype, taking into account that there is a Hardy-Weinberg equilibrium:

EE (p2) = (0.74) 2 = 0.547

Ee (2pq) = 2 × (0.74) (0.26) = 0.384

ee (q2) = (0.26) 2 = 0.067

We know that: (p² + 2pq + q² = 1)

replacing with the obtained data:

0.547 + 0.384 + 0.067 = 0.998 ~ 1

finally we can affirm that the population has a Hardy-Weinberg equilibrium

Answer:

Cytoplasmic tRNAs are found in the fluid inside cells (the cytoplasm). These tRNAs help produce proteins from genes located in the DNA in the nucleus of the cell (nuclear DNA). Although most DNA is nuclear, cellular structures called mitochondria have a small amount of their own DNA, called mitochondrial DNA. and mRNA is found in the nucleus and the cytoplasm in cells.

Explanation:

hope it helps : )

tRNA (transfer RNA) and mRNA (messenger RNA)  is found in the cytoplasm of the cell. DNA (deoxyribonucleic acid) is found in the nucleus of the cell.

tRNA plays a crucial role in translating the genetic information carried by mRNA into specific sequences of amino acids during protein synthesis. tRNA molecules are involved in bringing the correct amino acids to the ribosome based on the codons present in the mRNA.

mRNA is synthesized from DNA in the nucleus during a process called transcription. Once produced, mRNA leaves the nucleus and moves into the cytoplasm, where it serves as a template for protein synthesis. In the cytoplasm, mRNA is associated with ribosomes, which are the sites of protein synthesis.

DNA is primarily found in the cell nucleus, where it stores the genetic information of an organism. In some cases, a small amount of DNA can also be found in organelles called mitochondria (in eukaryotic cells) and plastids (in plant cells).

The theory of Continental Drift does not shows evidence about climate. Thus option A is correct.

Continental drift is defined as the idea that the positions of Earth's continents have changed over geologic time, giving the impression that they have "drifted" across the ocean floor.

It can also be defined as the continents moving horizontally at a huge scale in relation to one another and the ocean basins throughout the course of one or more geologic epochs.

The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.

The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift.

Thus, the theory of Continental Drift does not shows evidence about climate. Thus option A is correct.
