9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus
( b ) Micronucleus has role in conjugation in paramecium.
The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.
What Micronucleus role in conjugation in Paramecium?The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.
This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.
Therefore, Micronucleus has a role in conjugation in Paramecium.

Can viruses live through mutation and natural selection
Answer:
sure why not
Explanation:
as the virus mutates, it may increase, or lessen the chance for the virus to survive a battle against its host. like your regular living organisms (though keep in mind viruses are not considered living), some survive and some die due to natural selection and mutation.

This group of Bacteria can be pathogenic, ubiquitous in the environment whose cell walls are composed of peptidoglycan. So, the correct options are C, D and E.
What is Bacteria?
Bacteria are defined as ubiquitous, mostly free-living organisms that contain a single biological cell that constitute a large domain of prokaryotic microorganisms. Bacteria are a few micrometers in length that were among the first life forms to appear on Earth, and are present in most of its habitats.
Some bacteria are harmful that serve a useful purpose that support many forms of life, both plant and animal, and are used in industrial and medicinal processes. This group A mentioned in the above example of Bacteria can be pathogenic, ubiquitous in the environment whose cell walls are composed of peptidoglycan.

Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.
➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.
The plant will not remain healthy for long because:
[i] Exchange of gases will not take place.
[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.
[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.

What is biomass burned to produce
Answer:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.
It is estimated that the world human population reached 3 billion people in 1959 and 6 billion in 1999. Assuming a carrying capacity of 16 billion humans, write and solve the differential equation for Gompertz growth, and determine what year the population reached 7 billion. Was logistic growth or Gompertz growth more accurate, considering world population reached 7 billion on October 31,2011
Answer:
i ) Gompertz equation :
[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]
ii) The year that population reaches 7 billion is 2013
iii) The logistic growth was more accurate
Explanation:
i) write and solve the differential equation for Gompertz growth
Gompertz equation :
[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]
∝ = growth rate
k ( carrying capacity ) = 16 * 10^9
P(t) = population at time t
ii) Determine what year the population reached 7 billion
The year that population reaches 7 billion is 2013
solution attached below
iii) Determine if logistic growth or Gompertz growth was more accurate considering world population reached 7 billion on October 31,2011
The logistic growth was more accurate because the when Logistic growth model was used, the year in which the population reached 7 billion was 2010 and this value is more closer to 7 billion on October 31 2011 ( given value )

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.
Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

The typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate for about one day. After the reserve has been depleted during starvation, what other sources can be used to produce glucose
Answer:
Fats and proteins that are present in liver, kidneys, and muscles.
Explanation:
When the reserve of glucose is used by the body during starvation, our body uses fats and proteins that are present in liver, kidneys, muscles etc and convert these fats and proteins into glucose. There is high amount of fats and proteins present in our body which can be used when the glucose reserves depleted from the body during starvation so we can conclude that the fats and proteins are the sources that can be used to produce glucose for the body.

An entomologist is a person who studies, or is an expert in the branch of zoology. (A branch in zoology concerned with insects.)
Explanation:
:)))))))))help me plsss
Explanation:
1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.
2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.
3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.
