The hormone that regulates water reabsorption by the kidneys Group of answer choices only increases water permeability in certain portions of the kidney tubules. increases water permeability throughout the kidney tubules. only decreases water permeability in certain portions of the kidney tubules. decreases water permeability throughout the kidney tubules.
Answer: increases water permeability in certain portions of the kidney tubules.
Explanation:
The proximal convoluted tubule is the site in nephron where selective reabsorption of water and electrolytes like sodium and potassium ions occurs. From there water and other substances are reabsorbed and reenter into the circulation. This cause an increase in blood pressure and blood volume. Only the cells of the proximal convoluted tubule are permeable for this reabsorption process and they are stimulated by a hormone named as aldosterone.

Which of the three components that plants need do we provide?
Answer:
Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN).

Nuclear Fission is not a good source of energy. This is by reason of only 0.7% of the uranium being captured. This is small even if one doesn't mention that only 40% of that 0.7% is converted into usable energy. There are also chances that the power plant could explode during conversion. All of this evidence points to the fact that Nuclear Fission and Nuclear Energy themselves should not be relied on.

what is a genomic change based on definition?
Answer:
Genome size can increase by duplication, insertion, or polyploidization. Recombination can lead to both DNA loss or gain. Genomes can also shrink because of deletions. ... It is beneficial to an organism to rid itself of non-essential genes because it makes replicating its DNA much faster and requires less energy.
Explanation:
The study of genes and their function. Genomics aims to understand the structure of the genome, including the mapping genes and sequencing the DNA

Pesticide resistance is increasing, Farmers in the US tost 7% of their crops to pests in the 1940s, over the 1980s and 1990s, the loss
was 13%, despite more pesticides being used. It is estimated that 500-1000 pests have developed a resistance to pesticides. Consider
the diagram showing the evolution of pesticide resistance. Select ALL of the statements that do NOT accurately describe the
mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application hence insects with this trait become more prominent in the population
What is a pesticide?A pesticide refers to a chemical that is used to control the spread of pests in the farm.
The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population

a) They rely on fire as part of their renewal.
b) They have the same terrain.
c) They have the same soil composition
d) They have the same amount of precipitation
Answer:
They rely on fire as part of their renewal.
Explanation:
They rely on fire as part of their renewal. Which option describes the climate of temperate grasslands
They rely on fire as part of their renewal is common in grasslands, dry woodlands, and shrublands.
Grasslands, dry woodlands, and shrublandsTropical Grassland, Savanna & Shrubland is dominated by grasses and shrubs, with or without scattered trees. Some occur in climates too dry for the forest; others depend on soil conditions or fire, or both, rather than climate. The structure is a single, major grass or shrub stratum, or a mix of the two, with trees typically <10% cover, rarely with bare ground.Thus, we can conclude that grasslands, woodlands, and shrublands depend on fire they have these common characteristics.
