The rate at which molecules, such as water and oxygen, enter a cell is determined by the–

Answers

Answer 1

Answer:

Explanation:

Cell membranes act as barriers to most, but not all, molecules. Development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell. Cell membranes are differentially (or semi-) permeable barriers separating the inner cellular environment from the outer cellular (or external) environment.

Water potential is the tendency of water to move from an area of higher concentration to one of lower concentration. Energy exists in two forms: potential and kinetic. Water molecules move according to differences in potential energy between where they are and where they are going. Gravity and pressure are two enabling forces for this movement. These forces also operate in the hydrologic (water) cycle. Remember in the hydrologic cycle that water runs downhill (likewise it falls from the sky, to get into the sky it must be acted on by the sun and evaporated, thus needing energy input to power the cycle).

Why scientific naming is necessary?

Answers

Answer:

The correct answer would be - to communicate unambiguously globally.

Explanation:

In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.

Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.

if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart​

Answers

Answer:

Blue Eyes Are: Recessive

Explanation:

The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!

PLEASE HELP BEING TIMED Which is one piece of information that fossils in samples from Earth's crust reveal about Earth's history?
A. Changes in climate
B. Number if species at the specific time
C. Composition of Earth's core
D. Age of organisms when they died ​

Answers

Answer: changes in climate

Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

What are Fossils?

A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.

There are five types of fossils which are as follows:

Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossils

The fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.

Thus, change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

12) I think you need the equation as well:

Explanation: C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) --> 6CO₂ (Carbon Dioxide) + 6 H₂O (water) + ATP (energy)

1. Chloroplasts have thylokoids or stacked membranes like it has.

2. Photosynthesis is the process of converting light into usable energy.

3. That is the equation of photosynthesis. Their are different ways of writing this for example: 6 CO₂ + 6H₂O + light -->C₆H₁₂O₆ + 6 O₂ which is balancing the water. Check to see what your teacher used in the book/notes.

4. Light is required for photosynthesis and the sun is providing it.

5 and 6) The mitochondria uses both of these in its processes that were first made in photosynthesis.

7 and 8) Both are created by mitochondria and are used in chloroplasts.

9) Energy is produced in the mitochondria with help from the Chloroplast.

10) It is usually depicted with those lines in it.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.

Answers

Answer:

Phenotype: 3 black mice: 1 brown mice

Genotype: 1 BB: 2Bb: 1bb

Explanation:

This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.

If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:

BB, Bb, Bb, and bb

- The phenotypes of this cross is  3 black mice: 1 brown mice

- The genotypes of the cross is 1 BB: 2Bb: 1bb

How may mRNA be modified before it leaves the nucleus?

Answers

Answer:

The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.

Explanation:

mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.

How mRNA can be modified?

it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.

The practice of removing natural vegetation and replacing it with concrete and structures is known as urbanization. This is the correct answer to fill in the blank.

What are the primary factors causing urbanization?

Industrialization, commercialization, rural-urban migration, lifestyle changes, career opportunities, social advantages, etc. are the primary reasons of urbanization. The process of urbanization is when people move from rural to urban areas for a variety of reasons.

What results did urbanization produce?

Urban areas can expand due to a rise in the population or because people move there. Urbanization frequently causes habitat loss, deforestation, and freshwater extraction from the environment, which can reduce biodiversity and change species ranges and interactions.

Occasionally a new resistant strain of pathogen appears. The new strain may spread rapidly. Explain why

Answers

Answer:

Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.

Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

The heartbeat rate of an athlete during resting is lower than a non-athlete.
Explain why. [ 2 marks ]

Answers

Answer:  The heart muscle of conditioned athletes enlarges and strengthens.

Increased cardiovascular fitness causes real physical changes in the structure of the heart. The muscles in the heart wall thicken, and the heart pumps more blood with each beat. That increased efficiency means an athlete's resting heart rate falls to a level that could indicate trouble in a nonathlete. Many athletes don't realize that high levels of conditioning also cause heart symptoms that doctors might mistake for serious problems.
