why does the plasma cell have a well developed endoplasmic reticulum with lots of ribosomes
Answer:Within the cell, the endoplasmic reticulum synthesizes lipids and proteins. ... Proteins that are made in the cell for use by the cell-for instance, as channels in the plasma membrane-are made by the free ribosomes that dot the cytoplasm. Two types of endoplasmic reticulum are found in the eukaryotic cell.

Humans demonstrate significant diversity in biological traits, social characteristics, and agricultural practices. This diversity is reflected in physical attributes and social differences between societies, alongside the wide range of plants and animals cultivated for various environmental conditions.
Humans are considered a diverse population in many ways, but there are three main aspects that stand out.
Biological Diversity: With billions of humans on the planet's surface, human beings possess considerable biological diversity. Visible traits like skin color, or invisible genetic markers like blood type, contribute to this diversity. Within any subcategory, there will be more variation than that exists between different categories.
Social Diversity: Human social diversity arises from our societies' differing physical or social characteristics. These can vary greatly, resulting in a rich tapestry of cultures, languages, traditions, and social norms across the globe.
Agricultural Diversity: Humans have cultivated an immense diversity in domestic plants, animals, and fungi based on local needs and environmental factors. For example, potatoes have been bred into thousands of varieties to cope with specific soil and climate conditions—this mirrors cultural diversity within human populations.

The spores release from the gametophyte
The gametophytes grow directly from the sporophyte
The spores release from the male cones
I NEED HELP ASAP
Answer:
The correct answer is The gametophytes grow directly from the sporophyte.
Explanation:
Conifers are a group of plants that belong to what is called Pinophyta.
They abound in quantity in cold areas although many different types of this plant can also be found in tropical areas.
They are formed by live gemnosperm plants, this means that their seeds do not form in closed cavities but are "naked". These seeds are evergreen, this means that their leaves will not fall throughout the year and usually live for more than two years or produce other seeds again.
Gametophytes are haploid plants that are usually located in or below the soil and are responsible for producing gametes.
These grow directly from the sporophyte, which is the phase in which a plant reproduces by spores.
So we can say that the correct answer is The gametophytes grow directly from the sporophyte.
Answer:
The gametophytes grow directly from the sporophyte - third choice
B, green seeds
C, yellow-green seeds
D, some of each color
B. None of these describe natural selection
C. Organisms survive with random chance only
D. Organisms with favorable traits best fit for the environment survive and reproduce to pass on those traits
What is one advantage of their use as a green agricultural practice compared with conventional agricultural practices?
a. it prevents water pollution.
b. it prevents air pollution.
c. it prevents soil erosion.
d. it protects endangered species.
Answer:
A. It prevents water pollution
Explanation:
Conventional methods of agricultural pest control involves the use of pesticides. These pesticides are usually chemicals which are harmful to the organisms involved. However, since these chemicals are not easily degraded, they enter the runoff when rain falls, flowing into nearby streams and rivers, thereby polluting them.
However, with natural pest control methods like the use of ladybirds to destroy aphids, there would be no need for chemicals which will eventually pollute any nearby water environment.
