about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/

Winter wheat is planted in the early autumn, grows over the winter when the weather
is colder, and is harvested in the spring. As the temperature drops, the composition of
the cell membrane of winter wheat changes. Unsaturated fatty acids replace saturated
fatty acids in the phospholipids of the membrane. Why is this a suitable adaptation?
Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.
Explanation:
Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.
What are unsaturated fatty acids?Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.
Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.

In multicellular organisms, cell growth and division is very controlled. Some cells like muscle and _______ cells stop dividing after maturity. Other cells like ______ and blood cells grow and divide rapidly through life. _______ are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to ______.
The growth and development of an organism are dependent on the control and coordinated activities of the cells, tissues, and organs.
The correct blanks for the given paragraph are:
In multicellular organisms, cell growth and division are very controlled. Some cells like muscle and nerve cells stop dividing after maturity. Other cells like Skin and blood cells grow and divide rapidly through life. Cyclins are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to cancer.
The statements can be explained as:
The muscle and nerve cells stop dividing after maturity. The nerve cells lack centrioles, which play a crucial role in the division of cells. Thus, the nerve and muscle cells do not divide. The skin and blood cells divide continuously and throughout life. The cells when are damaged or dead, these cells replace them. Cyclins are the proteins, which regulate and activate the cell cycle by binding with the cyclin-dependent kinases.Cancer is repetitive and uncontrolled cell growth. It can be caused due to failure of regulation of cell cycle or any carcinogen exposure.
Therefore, the correct answers are nerve, skin, cyclin, and cancer.

Explanation:
"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

in which direction do particles in a solution move during passive transport
During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.
What is the importance of the different types of transportation?In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.
Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.
