Answer:
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
A group of scientists is trying to bring mammoths back by modifying elephant DNA. The new animals would have a mixture of elephant and mammoth genes. What will be the effect of the new genes?
A. The new genes will produce different proteins.
B. The new genes will prevent DNA replication.
C. The new genes will require gene therapy.
D. The new genes will not have RNA.
Answer:
C
Explanation:
Because when new genes are created they won't be able to adapt easily, so they will require gene therapy so they will be able to adapt easier.
Hope this helps you. :)
Have a good day!
The new genes will produce different proteins. Therefore, option (A) is correct.
By modifying the DNA of elephants to include mammoth genes, the scientists aim to introduce genetic variations that were present in the woolly mammoth. These genetic variations would result in the production of different proteins compared to the proteins produced by elephants.
Proteins are essential molecules that perform a wide range of functions within living organisms, including structural support, enzymatic activity, and regulation of biological processes. Therefore, the introduction of new genes from mammoths would lead to the production of different proteins, potentially affecting various traits and characteristics of the modified elephants.

How can a mutation that causes a change in the structure or function of a protein be beneficial to an organism?
Answer:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression.
Explanation:
Mutations can result in structural alterations in a gene's translation, as well as a decrease or complete loss of the gene's function.
Because a change in the DNA sequence affects all copies of the encoded protein, mutations may be extremely detrimental to a cell or organism.
Genes have a crucial part in an organism's development and function. Mutations can result in structural changes in the decoding of a gene, as well as a decrease or complete loss of its activity.

Answer: hydrosphere interacting with the geosphere
Explanation: This is actually a very simple question. A stream is clearly from the hydrosphere, as originated from the greek root hydro, meaning water, and rocks are from the geosphere, as geo is the greek root for earth. A water source eroding a earth source is the hydrosphere interacting with the geosphere.
Juanita learns that gray tree frogs and green tree frogs both live in the southern United States. The gray tree frogs live in forests and blend in with the bark on the trees. The green tree frogs blend in with the tall reeds and grasses of the wetland areas. Natural selection helps the gray tree frogs in the forests and the green tree frogs in wetlands.
Natural selection is affected by which three factors?
A. reproduction
B. evolution
C. variation
D. overproduction
E. mechanism
F. competition
Answer:
A.reproduction
B.Evolution
F.competition
Explanation:
Variation, reproduction, and competition are the three factors that influence natural selection and drive the evolution of species over time.
What factors affect natural selection?Natural selection is affected by three factors: variation, reproduction, and competition.
Variation refers to differences among individuals within a population. In this context, the different coloring and habitat preferences of the gray and green tree frogs would be considered variations.Reproduction is the process by which organisms produce offspring, and it is a crucial component of natural selection because it allows advantageous traits to be passed on to future generations. In the case of the tree frogs, individuals with coloring that helps them blend in with their environment are more likely to survive and reproduce, thereby passing on their advantageous coloring to their offspring.Competition refers to the struggle among individuals for resources such as food, mates, and habitat. In this context, the competition between the gray and green tree frogs for resources in their respective habitats would affect the outcome of natural selection.Learn more about natural selection, here:
