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.

explain how the products of photosynthesis are stored leaves!
Answer:
The products are stored in the form of starch because glucose is soluble
Explanation:
Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

b. biosphere interacting with the biosphere
c. hydrosphere interacting with geosphere
d. blasphere interacting with the atmosphere
!answer quick will give branliest!!
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:

What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

Given the following phylogenetic tree, which evolutionary event occurred most recently?
A.) development of different forms of symmetry.
B.) development of tissues.
C.) each of these traits evolved at the same time.
D.) protostome and deuterostome development.
Answer:
Option-D
Explanation:
A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.
The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.
The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.
Thus, Option-D is the correct answer.
