during the light reactions of photosynthesis protons are actively transported:
Answer:
During photosynthesis a proton gradient is maintained by the active pumping of protons across the thylakoid membrane into the lumen of the thylakoid. ... The light dependent reactions require photosynthetic pigments that are found embedded in the thylakoid membrane.
During photosynthesis a proton gradient is maintained by the active pumping of protons across the thylakoid membrane into the lumen of the thylakoid.
What is light reaction?The initial step of the photosynthesis process is called the light reaction, and it is at this stage that solar energy is turned into chemical energy in the form of ATP and NADPH. Both the protein complexes and the molecules of the pigment contribute to the synthesis of NADPH and ATP.
The thylakoid discs are the locations of the light response that takes place. There, oxygen (O2) is produced as a byproduct of the oxidation of water (H20). After being released from water, the electrons are then transferred to ATP and NADPH. Outside of the thylakoids is where the dark reaction takes place.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population
Explanation:
Why anti-poaching?Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.
In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.
It is therefore our call to stop the slaughter of rhinos with all our might.

(D) a temporary increase in the arctic hare population to more than 425 individuals
(E) a mutation that introduces a new fur color to the arctic hare population
A temporary increase in the arctic hare population to more than 425
individuals.
Hares are among the primary consumers as they are herbivores while foxes
are secondary consumers which feeds on the hares.Foxes will hunt the
hares for food which will drastically reduce their population
Increasing their population by 425 individuals with the hares having a
population of 400 will surely decrease their carrying capacity in the tundra

Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.
Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.

Explain the variation and distribution of expressed traits in a population in regards to the Sama-Bajau people and enlarged spleen. How does having an enlarged spleen benefit?
It is common for Sama-Banjou people to have an enlarged spleen, this is the result of environmental factors as a larger spleen helps them to dive better.
In most people, an enlarged spleen is not common and it is often related to specific conditions and diseases. Due to this, the percentage of people with an enlarged spleen is quite low.
Despite this, it has been found many Sama-Banjou people have an enlarged spleen and this is the result of environmental factors. Indeed, Sama-Banjou people have relied on diving to survive for centuries as they collect seashells from the seafloor.
This condition has led to bigger spleens, these bigger spleens increase the amount of oxygen while diving, and therefore, help them to dive for longer periods.
