Answer: More
Explanation: Assuming the environment is one of lighter colors like snow, the mice would be more likely to survive because their fur would help them camouflage into their surroundings. Thus, making them less susceptible to predator's.
The mutation in the colder temperature which causes their fur to turn white is more likely to help them in surviving better in this environment. Thus, the mutation is advantageous.
What are Mutations?A mutation is an alteration in the nucleic acid sequence such as DNA or RNA of the genome of an organism, such as the virus, or extrachromosomal DNA molecule which is present in the mitochondria and chloroplast of a eukaryotic cell. Viral genomes are the genomes which contain either DNA or RNA as their genetic material.
A mutation in a few brown mice had a mutation which caused the fur to turn white in colder temperatures. This mutation will increase the chances of survival of the organism as this help in camouflage. Camouflage is called as cryptic coloration, it is a defense or tactic which organisms use to disguise their appearance, usually the one which help to blend in with their surrounding environment.

Which of the following statements is true?
A. The karyotypes for a male human and a female human will look exactly the same.
B. The number of chromosomes in all organisms is the same.
C. Sometimes, a single gene can influence many traits.
D. There are more chromosomes in a cell than there are genes.
Answer:
the answer is C
Explanation:
Sometimes, a single gene can influence many traits in an organism. This is possible due to gene interactions. Thus, the correct option is C.
What is Gene interaction?Genetic interaction is the set of functional association between different genes in an organism. Genetic interactions are the relationship is called as epistasis. Epistasis is the interaction of non-allelic genes where the effect of one gene in an organism is masked by another gene to result either in the suppression of the effect of that gene or they both combine to produce a new trait or character.
In epistasis, the gene which masks another gene is called as epistatic gene, and the gene whose expression is being masked is termed as hypostatic gene. Epistasis is also referred to as the inter-genic or inter-allelic gene interaction.
Therefore, the correct option is C.

Optimum germination conditions differ between species. Sometimes this depends on the evolutionary history of the plant species. One species has higher germination rates when the seeds are exposed to soil with ash present. This is an example of _______________.
Answer:
seed dormancy
Explanation:
Seed dormancy represents an evolutionary adaptation capable of preventing seed germination. Seed dormancy enables to overcome unfavorable periods for germination, thus being critical for plant survival. In this regard, it has been shown that in plants living in fire-prone ecosystems (such as, for example, montane forest species), seed germination may be triggered by ash after fire, which is required to break seed dormancy.

Water vapor inside magma increases its explosiveness.
true or fasle
Answer: True.
Explanation: When the water vapor bubbles try to rise they are impeded by the linkage of silica chains in the magma and can rise only slowly. The rapid change in confining pressure as the magma body rises to the surface causes the dissolved water vapor bubbles to expand and escape explosively.
In Holstein cattle the spotting of the coat is due to a recessive gene, while a solid-colored coat is dominant. Two heterozygous solid animals are crossed. What would be the expected genotypes and phenotypes of the offspring?
Answer:
In Holstein cattle when two heterozygous animals are crossed for the characteristic coat color, the offspring will be individuals with solid coat and spotted coat in a 3:1 ratio.
Explanation:
Since in Holstein cattle the solid color coat is dominant (S), and the spotted coat is recessive (s), each heterozygous individual has the genotype Ss.
The result of crossing two individuals of Holstein cattle heterozygous can be seen in Punnet's Square:
Ss X Ss
Alleles S s

Answer: The options are not given, here are the options.
.a.prophase
b.prometaphase
c.metaphase
d.anaphase
e.telophase
The correct option is C.
Metaphase.
Explanation:
It is metaphase because during metaphase, the chromosomes lined up together and the two sister chromatids join to a particular spindle fiber. The microtubules them bring the sister together chromatids from the opposite spindle poles. The kinetochore microtubules capture the sister chromatids back and forth til they are able to form alignment along the equator of the cell which is called the equatorial plane.
Which event occurs prior to speciation?

B) A major change on earth takes place.
C) A population is divided.
D) Organisms of different populations join together.
Answer: C.
Explanation:
I hope this helps plz tell me if its wrong so i can fix it :)
The event that occurs prior to speciation is that a population is divided, which is Option C, as when a population is divided by a geographic barrier such as a mountain range, river, or sea, then this type of speciation takes place.
What is speciation?Speciation is the process by which a single ancestral species gives rise to two or more descendant species, and it occurs when populations of the ancestral species become separated and evolve independently, accumulating genetic differences over time by a physical or geographical barrier along with mutation, genetic drift, or natural selection that separates a population into two or more groups that are no longer able to interbreed leads to speciation.

(Q029) Which of the following statements is FALSE? Group of answer choices Formins promote the formation of unbranched actin filaments. Actin filaments are usually excluded from the cell cortex. Integrins are transmembrane proteins that can bind to the extracellular matrix. ARPs can promote the formation of branched actin filaments.
Answer:
- Actin filaments are usually excluded from the cell cortex
Explanation:
In eukaryotic cells, actin proteins polymerize in order to form filaments. These actin filaments can be localized beneath the plasma membrane, where they form a network that helps to provide mechanical support. This network localized on the inner face of the plasma membrane is called 'cell cortex', which is a specialized structure that is attached to the cell membrane by Ezrin, Radixin and Moesin (ERM) proteins. The cell cortex plays key roles by controlling the cell shape, cell morphogenesis and membrane behavior.
The statement "Actin filaments are usually excluded from the cell cortex" is false.
In point of fact, actin filaments are most frequently discovered in the cell cortex, which is a highly specialised region that is located close to the plasma membrane.
Actin filaments are abundant in the cell cortex, where they serve as a source of structural support and contribute significantly to the processes of cell shape maintenance, cell adhesion, and cell migration. Actin filaments play a pivotal part in these cellular functions.

why is the cell membrane called the fluid mosaic model? quick if you can please
Answer:
The fluid mosaic model of the cell membrane is how scientists describe what the cell membrane looks and functions like, because it is made up of a bunch of different molecules that are distributed across the membrane. ... The movement of the mosaic of molecules makes it impossible to form a completely impenetrable barrier.
Explanation:
The cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer.
According to this fluid mosaic model, membranes consist of a lipid bilayer (essentially a double layer of phospholipids) in which various proteins are embedded.
The lipid bilayer is the base of the membrane, proteins are normally found "dissolved" in the lipid bilayer, they act as mediators or facilitators of almost all the functions of the membrane, either by transporting specific molecules.It also highlights that the membranes are fluid, dynamic and their components mobile, a very important characteristic that allows the existence of transitory interactions.Finally, this model of the membrane structure proposes that the arrangement of its components is asymmetric and they can have numerous associated carbohydrates.Therefore, we can conclude that the cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer..
