In passive transport, molecules move__ the concentration gradient.

Answers

Answer:

In passive transport, molecules move with the concentraction gradient.

Explanation:

If molecules moved against it would be active transport.

Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."

What is passive transport?

Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.

The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.

It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.

Therefore, the ions move down the concentration gradient in the passive transport.

Increased deforestation reduces the habitat for an arthropod species preferred by an island reptile. Which of the following descriptions predicts the most likely outcome for these two species?

The reptile population increases as arthropods are confined to smaller sections of the island.

Island arthropods decrease as the reptile population increases.
Island arthropods and reptiles both increase in the island habitat.

Question 6

Which statement describes a factor in the island biogeographical model?

Dispersing species are more likely to find smaller secluded habitats
Smaller populations are less likely to go extinct
Large islands have less available niches for immigrating species
Islands closer to the mainland have greater colonization

Species-area effect
Rescue effect
Target effect
Time/stability hypothesis
I and II
II and III
I, II, IV
I, II, III, IV

Answers

Answer:

Ecological tolerance refers to the ability of an organism, or animal to be able to adapt and survive changing environmental conditions.

The combination of factors that would result in an island community with the lowest ecological tolerance would be option B Introduction of invasive species, increased deforestation because with the introduction of invasive species, there would be more competition for natural resources such as food, water, sunlight; and with increased deforestation, there is greater chances of soil erosion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.

The reptile population decreases as arthropods decrease with their habitat

Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?

Answers

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.

WHAT IS MITOSIS:

Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell.

Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent.

In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.

The tropical rain forest biome has some of the highest biodiversity on earth how would a decrease in the biodiversity due to deforestation or other factors affect the large biosphere

Answers

Answer:

Negatively.

Explanation:

A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.

The decrease in biodiversity due to deforestation and other factors in the tropical rainforest biome will negatively affect the biosphere. Thus, the effect will be negative.

What is the biosphere?

The biosphere also called the ecosphere is the sum of the total life or the ecosystem. It includes the part of the planet where life is inhabitants. It may include a mountain, roots, dessert, oceans, etc. It is interrelated to biodiversity.

If the biodiversity of a place gets declined due to factors like deforestation, pollution, poaching, natural disasters, etc. then it will affect the ecosystem. If the stone species are lost then it will have a detrimental effect on the ecosystem.

These negative consequences disrupt the food chain and will result in affecting every organism. This chain of disruption will cause an overall loss to the biosphere.

E. coli Is a species of bacteria that causes many different Infections in humans. Certain E. coli strains have developed resistance to antibiotics,
making Infections with these strains difficult to treat. How do bacteria such as E. coll, which reproduce asexually, galn new tralts such as
antibiotic resistance?
O A. by adapting to changes in environmental conditions without undergoing changes in their DNA
OB. by mutating their DNA in response to environmental conditions to gain beneficial traits
OC. by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
OD. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population

Answers

Answer:

The correct answer would be B

Explanation:

Antibiotic resistance in bacteria develops in response to the environment in which the bacteria survives.  

The antimicrobial resistance trait is acquired by any species of bacteria through one of the two ways that are either by making changes in their DNA sequences or through horizontal gene transfer mechanisms.

In the given E. coli gained the trait to develop resistance against antibiotic by making changes in their DNA as once the gene is altered or mutated, the trait can be passed on to the offsprings.

Therefore, Option-B is the correct answer.

Answer:

B. By mutating their DNA in response to environmental conditions to gain beneficial traits

Explanation:

Through the process of natural selection, bacteria such as E coli can gain new traits that benefit them.

This can occur when a DNA mutation occurs, where the mutated gene is actually beneficial to respond to environmental conditions.

Then, these bacteria with the gene will survive and produce more offspring with the same gene. This is how E coli can develop antibiotic resistance.

So, B is the correct answer.

Some thunderstorms have a chance of producing hail and/or tornadoes. Localized heavy snow showers during the winter may also include thunder and lightning. Additionally, it frequently delivers heavy rain as well as violent gusts.

Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, and strong gusts of wind.

Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form.
