Explain why DNA Sequencing proves that all species have a common ancestor

Answer:

Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.

A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.

A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.

By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.

Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.

Thus, the correct option is A.

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

1÷4×100 = 25

Answer:

Such offspring are called hybrid offspring. Furthermore; within such hybridization process, if male is a lion and female is a tiger (tigress) then the hybrid offspring is termed as a liger. Vice-versa; if the male is a tiger and the female is a lion (lioness) then the hybrid offspring is called a tigon.

Answer:

Answer:

Reasons why they're different :

Explanation:

1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).

2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.

3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.

4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.

5. Unlike mitosis, meiosis differs in males and females.

6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.

Answer:

B.

Explanation:

In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.

There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.

Intraspecific competition is a competition between two living beings of the same species.

The monarch butterfly and the queen butterfly both belong to the same species- danaus.

Therefore, option B is correct.

The answer is :

B. Neutron

La citocinesis ocurre al final del ciclo celular después de la mitosis o meiosis. En la división de células animales, la citocinesis ocurre cuando un anillo contráctil de microfilamentos forma un surco de escisión que pellizca la membrana celular por la mitad. En las células vegetales, se construye una placa celular que divide la célula en dos.

Answer:

Mitosis creates more diploid cells by copying each chromosome and moves it to the other side of the cell.

Explanation:

This lets the cell get divided straight down the middle.

Answer:

Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.

Answer:

It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.

Explanation:

Answer:

Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

Explanation:

So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.

Lets think about what can cause a lack of increase?

A decrease can cause this.

Or a slow in the rate of increase.

Now lets look at our selectable answers and see if any of them would fall under these two things.

First up is fewer deaths.

Well, fewer deaths basically means less of a decrease in population.

This is the opposite of decreasing the populatin count, and would instead raise it.

Next we have a limit in food supply.

This would cause a organism to starve and die.

So this would cause a decrease in population count.

So B is one of the answers

Next up is competition with other species.

When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.

So this would also cause a large decrease in population count.

This makes C one of the answers

Next is increase in birth rates.

This would cause more organisms to be born of a species, basically increasing the population count.

This is the opposite of a decrease in  population.

Next we have competition for space.

This is very similar to answer C, and the outcompeted species dies out due to lack of space.

So E is one of the answers

Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.

However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.

So although major storms decrease populations, they dont actually limit them.

In the end:

B is correct

C is correct

E is correct

Answer:

The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"

Explanation:

A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.

In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.

A possible hypothesis for this situation is that tank 1 contains denitrifying bacteria, tank 2 contains nitrite nitrifying bacteria, and tank 3 contains ammonia nitrifying bacteria.

A hypothesis, which is a common term used in experiments refers to a possible explanation for the results or phenomenon observed. In this case, a hypothesis needs to focus on the type of bacteria that are present in each of the tanks.

This means that to write a hypothesis we need to relate the type of bacteria to each of the tanks.

Explanation:

Answer:

The correct answer is - B. An allele present in all members of a population.

Explanation:

A homzygous variant or allele for all the members of a particular gene is a fixed gene and is the only variant that presents in all the population for that gene.

It takes place when there is all other alleles become extinct and only one remains. The allele frequency of this allele is always 1.00 in the population which means only one allele is present on the locus.
