Answer:
Purse seines
Explanation:
Purse seines are used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel. A vertical net 'curtain' is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish, rather like tightening the cords of a drawstring purse.

what are some drawbacks to using mice in genetic studies?
Answer:
One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.
hope this helps
Explanation:
Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.
Why it's bad to use mice as an experiment:
The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

What term describes the total mass of trees, shrubs, herbaceous plants, and grasses present in a given forest on a given day
The term best describes the mass of the above-ground vegetation in a given forest would be the standing crop.
The standing crop of a forest specifically refers to the mass of all the living plant materials present in the forest at a particular time ranging from the biggest of trees, shrubs, herbs, to the tiniest of grasses.
Standing crop is as opposed to biomass in that the latter refers to the total mass of organic materials from the living and dead plants derivable from the forest.

The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment
Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.

The weathering of rock caused by salt is
B
Explanation:
It occurs when water dissolved with salts seeps into the cracks of a rock. When the water slowly evaporates it leaves behind crystals of salts. When the rock is heated, the salts also expand and create pressure within the cracks, widening them and causing the rock to split.
