If a human has an extra copy of one pair of homologous
chromosomes, how many chromosomes will she have in total?

Answers

Answer 1

Answer:

48 chromosomes

Explanation:

The genetic condition described in the question is referred to as ANEUPLOIDY, which is a chromosomal disorder. ANEUPLOIDY occurs when there is an extra or missing copy of a chromosome in the normal set of chromosomes. It occurs mainly due to the fusion of an abnormal gamete.

A karyotype shows that human cell consists of 46 chromosomes in total I.e. 22 pairs of body and 1 pair of sex chromosomes. A human is a diploid organism I.e. contains two set of chromosomes. This means that one set of chromosomes (haploid, 23 chromosomes) is contributed by one parent.

Therefore, in a case whereby, an extra copy of a pair of homologous chromosomes is contained in the genome of a human. Hence, this will be 2n + 2 which means 46 chromosomes plus two extra chromosomes = 48 chromosomes. This ANEUPLOIDY likely resulted from the fusion of two abnormal gametes that are n+1 each.

Cellular respiration involves a reaction between glucose and oxygen to form. A.water.
B. energy.
C. carbon dioxide.
D. all of these.

Answers

Answer: D

Explanation: THE PRODUCTS FOR cellular respiration are water CO2 AND energy

Cellular respiration involves a reaction between glucose and oxygen to form water, energy in the form of ATP (Adenosine triphosphate), and carbon dioxide. Thus, the correct option is D.

What is Cellular respiration?

Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor such as the oxygen atom to produce large amounts of energy, to drive the bulk production of ATP (adenosine triphosphate) in the mitochondria of cell.

In the process of cellular respiration, glucose molecules and oxygen react to form ATP molecules. Water and carbon dioxide are released as byproducts from this reaction. The three stages of aerobic cellular respiration are glycolysis, the Krebs cycle, and oxidative phosphorylation.

Therefore, the correct option is D.

can someone please help me with this question

Answers

Answer:

You got it right, Its answer choice D

Explanation:

Because if the organism is performing cellular respiration, it will be taking in oxygen causing it to decrease, while carbon dioxide will be increasing  

Answer:

D.) the organism is performing respiration because the carbon dioxide is increasing and the oxygen is decreasing.

Explanation:

Over time, when an organism, (for example, a cat) is breathing in a confined space for a long amount of time, the air in the space will have more carbon dioxide in it.

This is because as the cat breathes in the oxygen, it is exhaled as carbon dioxide.

Therefore, after a long period of time that cat will have breathed in a lot of the oxygen which is replaced with carbon dioxide.

What are some of the causes that disrupt the natural balance of the ecosystem? ridding the soil of decomposers removing predators by hunting overpopulation of predators breeding hybrid plants removing prey by transplantation

Answers

Answer: overpopulation of predators

Explanation: Overpopulation of predators is the correct option. Predators are the organisms which kill other organism so as to obtain them as food. The organism being killed is called as the prey.

If the population of the predators increase this will lead to the extinction of many species of prey. As it is evident that every organism in the ecosystem has a typical role to play. Therefore, it can be said that role of prey will not be performed and this may lead to disturbance in the ecological balance.

Final answer:

To measure the volume of water in a graduated cylinder, follow these steps: place the cylinder on a flat surface and read the volume from the bottom of the curved surface (meniscus).

Explanation:

To measure the volume of water in a graduated cylinder, the correct procedures are:


He should place the graduated cylinder on a flat surface to ensure stability and accurate readings.

He should take the reading from the bottom of the curve of the surface of the water (the meniscus).

These procedures help to ensure accurate measurements by minimizing human errors and taking into account the meniscus, which is the curved surface of the liquid in the graduated cylinder.

What is the definition of "population growth?" Be specific! *

Answers

Answer:

Population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.774 billion in 2020.

Explanation:

Final answer:

Population growth is the increase in the number of individuals in a population due to more births and immigration than deaths and emigration, which is measured by the population growth rate.

Explanation:

Population growth refers to the increase in the number of individuals in a given population over a specific period of time. This growth can occur due to various factors, such as a higher number of births than deaths, and the process of immigration, where individuals move into the region. Conversely, populations can decrease through deaths and emigration, where individuals leave the area. These factors together determine the population growth rate, which measures how quickly the population size changes.

Population structure, which includes the age-sex distribution, along with fertility, mortality, and migration rates, also plays a crucial role in influencing the population growth. It is important to note that populations don't always grow; their growth rates can be affected by the local economy, available resources, and environmental conditions. Demography, the study of populations, is essential to understand and manage these growth dynamics.

b)primary succession after a volcanic eruption
c)secondary succession after a controlled fire
d)secondary succession after a volcanic eruption

Answers

Primary succession after a volcanic eruption would be the most accurate title for this picture. So, the correct option is B.

What is Primary succession?

The process of ecological succession known as primary succession occurs where there was previously no biological community, such as on bare rock, in sand dunes, or after a volcanic eruption. Pioneer species that can colonize bare rock and soil, such as lichens and mosses, typically initiate primary succession by doing so.

As these pioneer species slowly decay and decompose, they add organic matter to the soil and promote colonization by other plants and animals.  The primary succession process can take hundreds or even thousands of years to achieve a stable climax community, which is an organism community that is mostly self-sustaining and adapted to its environment.

So, the correct option is B.

Find the force of an object with mass(m) as 600kg and acceleration as 50m/s^2

Answers

Answer:

F= 3000N=3x10^3N

Explanation:

According to Newton's second law the force applied on an object causes an acceleration of a, and the relation btw the force and the acceleration is defined as follows;

F=m.aF=(60kg)x(50m/s^2)F= 3000N=3x10^3N

Final answer:

The force of an object with a mass of 600kg and an acceleration of 50m/s^2 is 30000 Newtons.

Explanation:

The force exerted by an object can be found using Newton's second law of motion, **F=ma where 'F' is the force, 'm' is mass, and 'a' is acceleration. In this case, the mass 'm' is 600kg, and the acceleration 'a' is 50m/s^2.

By substituting the given values into the equation, we get:
F = (600kg) * (50m/s^2) = 30000N.
