A heritable change in a person's genetic makeup is referred to as a mutation. Changes can be substantial or negligible. Chromosomes or chromosome parts may be lost, added, duplicated, or rearranged in significant alterations. Thus, option B is correct.
What mutation in a gene results in an animal?High-energy sources like radiation or chemicals in the environment can both result in mutations. They may also emerge on their own during DNA replication. The two main kinds of mutations are chromosomal abnormalities and point mutations.
Mutations can alter an organism's phenotype, which is its outward appearance, or they can have an impact on the way DNA encodes the genetic information (genotype). When mutations happen, they might kill an organism completely or only partially.
The likelihood that a gene mutation will cause an animal to be unable to produce the protein necessary for muscles to contract is that the animal will perish before producing any progeny.
Therefore, The animal will die before having any offspring.

An allele arises in a population that helps individuals digest cellulose. While the allele starts in only one organism, it increases in allele frequency because it allows organisms that carry it to reproduce more. What is this an example of
ANSWER: A NATURAL SELECTION.
EXPLANATION:
When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .
However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.

What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Hope it helps
Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.
Answer:
Autotroph
Explanation:
An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.
According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.
What is speciation? What are the causes of speciation? How does isolation lead to speciation?NO LINKS PLEASE
The biological species concept tells us that organisms belong to the same species if they can breed to produce fertile and viable offspring. Speciation is therefore the development of reproductive isolation between individuals of an original population.
This can occur in 2 different ways:
1. Allopatric speciation. This is when speciation occurs due to some sort of geographic barrier separates a population into 2 groups. These two groups can then undergo genetic divergence, where each group grows increasingly dissimilar genetically due to random mutations and natural selection acting separately in each group, or from processes such as genetic drift. It is important to recognize that the lack of gene flow between these two groups contributes to the genetic divergence of the groups. Genetic divergence can lead to prezygotic and post-zygotic barriers which prevent production of fertile/viable offspring between the 2 groups. Each of these populations now represents a new species, whose gene pools are completely separate from one another.
2. Sympatric speciation. This is when speciation occurs without the presence of any sort of physical/geographical barriers. Truthfully, this is a much less common occurence. However, it is thought that sympatric speciation can occur as a result of strong divergent selection. Sympatric speciation may also occur as a result of a polyploid individual being introduced into a diploid population.
Isolation leads to speciation by preventing gene flow between 2 groups of an original population, allowing genetic differences between the groups to accumulate over time (via natural selection, genetic drift, etc.). Over time, the accumulation of these genetic differences may result in reproductive isolation between the 2 groups, causing these two groups to be committed to separate evolutionary paths.
Answer: So, how might speciation happen?
Explanation:
Speciation describes a situation where a population in a species becomes so different that it can no longer successfully interbreed with other populations of the ‘same’ species.

➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.
