An illustration of a cell interacting with its environment is provided.
The illustration best represents which of the following ?
A.Water moving into a cell by the process of osmosis
B.Passive transport of solute into the cell by diffusion
C.Active transport of solute into the cell using energy
D.Water leaving the cell by the process of osmosis
Answers
In the cell, there is passive transport of solute into the cell by the process of diffusion. So the correct option is B.
What is diffusion?Diffusion is a phenomenon that happens when molecules move randomly and results in a net movement of matter from a high concentration area to a low concentration area. The scent of a flower that swiftly fills a room's quiet air is a common illustration.
Thermal energy is transferred or diffused from a higher to a lower temperature through the process of heat conduction in fluids. In order for a nuclear reactor to function, neutrons must diffuse through a material that frequently scatters them but only sometimes absorbs them.
It is discovered that the concentration gradient is proportional to the rate of flow of the dispersing material. If c is the substance's concentration, x is perpendicular to this reference area, and D is the constant of proportionality, then j = D(dc/dx); dc/dx is the rate of growth of concentration in the direction x, and the minus sign denotes that the flow is from higher to lower concentration. The diffusivity, or D, controls the rate of diffusion.
Therefore, the correct option is B.

4.A student is conducting research on the impact of humans on whooping crane populations in the North America. Which statement best supports the student’s claim that animals have been positively impacted by human intervention?(1 point)
Captive-bred whooping cranes have been introduced to natural environments.
In the 1800s, North America was home to over 1,000 whooping cranes.
In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty.
Although the hunting of whooping cranes was criminalized, their numbers continued to decline.
Answers
Explanation:
1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
Climate change leads to salinity, the python is responsible, the populations were affected due to human actions that caused environmental changes. In the early 19th, America and Canada signed a migratory bird treaty.
What is the explanation of the above answers. ?The Everglades is a wetland preserve of southern Florida and is made up of coastal mangroves. Due to the impacts of the climate the region is under threat from the rising seawater and hence salinity is also one of the factors that are due to climate change.
The python is a species that is responsible for the 99% for drop in the level of the possum population of the everglades. The native Burmese's python is a cause of animal decline they are similar to the cranes because both of them are wiped by the environmental changes made by man.
As per the research of the student the impact of human whooping cranes in North America is due to the early 19th century both the US and Canada signed the migratory bird treaty.

Answer:
The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.
And that is why the neuquen has the warmer air temperature!

Explain why siblings may share similarities but are not identical.
Answers
Answer:
recombination
Explanation:
Since of recombination, kin as it were share approximately 50 percent of the same DNA, on normal. So whereas organic kin have the same family tree, their hereditary code can be distinctive in at slightest one of the zones looked at in a given test. That's genuine indeed for intimate twins.
Siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.
What is the reason behind a non-identical sibling?Siblings are not identical because each parent can contribute different variations of genes to each child, resulting in unique combinations of genetic material. Moreover, the process of meiosis, which is the formation of reproductive cells, is a random process, meaning that the chromosomes from each parent can mix in different ways during the formation of the offspring's cells. Therefore, each sibling inherits a unique combination of genetic material, leading to individual differences in physical and behavioral traits.
Hence, siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answers
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.

Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324

Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.
