Answer:

When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

Nitrogen fixation is the process by

Which nitrogen is taken from its stable

Gas form (N2) in air and chances into

Other nitrogencompounds (such as ammonia,

Nitrate and nitrogen dioxide) useful of other

Chemical processes.

B.) Nitrification

The process by which bacteria is soil and water

Oxidize ammonia and ammonium ions and form

Nitrites and nitrates. Because the nitrates can be

Absorbed by more complex organisms.

C.)Assimilation

Cultural Assimilation is the process of a group's language

And/or culture coming to resemble those of another group.

D.) Denitrification

The loss of removal of nitrogen or nitrogen

Compounds specifically :reduction of nitrates

Or nitrites commonly by bacteria (as in soil) that

A graduated cylinder containing 40 mL of water has a total mass of 60 g. A solid object carefully lowered into the graduated cylinder. The level of the water rises to 70 mL. The total mass of the cylinder, water and object is now 95 g what is the mass? volume? and density

Answers

Answer:

The correct answer is -

A) 35 g

B)30 mL

C)1.66666666666667g/ml3

Explanation:

Given:

mass of graduated cylinder containing 40 mL = 60 g

volume of water = 40 ml

increase in the level of water = 70 ml

increase in mass = 95

Solution:

A) mass of object -

increased mass - initial mass

90 - 60 = 35 g

B) volume of object

increased volume - initial volume

70 - 40 = 30 mL

C)  density d=m/v

d=35/30

d=1.66666666666667

What is photosynthesis​

Answer:

The process of a plant converting sunlight, carbon dioxide and water into food

Explanation:

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Simplified definition -> the branch of chemistry that deals with inorganic compounds.

Longer definition -> Inorganic science is the part of science which examines the components, and inorganic mixtures. Inorganic science can be characterized just as all science which isn't natural science. Natural science is essentially the investigation of carbon compounds.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes

Answers

Answer:

3/16

Explanation:

This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).

According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

* Attached earlobe, wet earwax (A_E_) = 9/16

* Attached earlobe, dry earwax (A_ee) = 3/16

* Free earlobe, wet earwax (aaE_) = 3/16

* Free earlobe, dry earwax (aaee) = 1/16

Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.

The correct answer is - biodiversity is a good thing.

Explanation:

Biodiversity is the variety of types of life including all organisms present on earth or if related to a specific area then the ecosystem. Biodiversity helps in boosting the productivity of the ecosystem and each organism of the ecosystem plays an essential role in it.

The higher the biodiversity more chances of survival of organisms. Biodiversity provides oxygen, water and soil that helps to strengthen the ecosystem.

Reproductive isolation occurs when

A- some catastrophic event greatly reduces the size of the population

B- The gene pool of different populations have become very diversified

C-members of different populations can no longer meet successfully

D-small numbers of individual moves and starts in new population

Answers

Answer:

The correct answer is - C. members of different populations can no longer meet successfully.

Explanation:

Reproductive isolation is the process that occurs when two or more species or populations are not able to interbreed. The mechanisms or properties that are used to preventing individuals of separate species from mating called Reproductive isolation mechanisms.

The different barriers can cause this reproductive isolation such as different mating seasons. These barriers could be behavioral or temporal or ecological isolations.

Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.

What are the features of punnett square method?

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.

The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.

A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.
