Cactus plants, which grow in deserts, have a thick waxy coating that helps prevent water loss. The plants' sharp
spines provide protection from predators. Which of the following statements best explains why cactus plants
evolved to have these traits?
Answer:
C
Explanation:
Survival of the fittest shows that plants/animals with traits better suited for survival in their environments usually pass those traits to their offspring to help them survive.
Cactus plant with these traits were better able then other cactus plant to survive and pass these traits on to their offspring.
How do cacti adapt to the desert?Stems that can store water. Widespread or very deep root systems that can collect water from a large area or from very deep underground.
Why are cactus found in desert region?Cactus is found in dry and hot areas where rainfall is minimal and the land is arid. Their leaves are evolved into thorns to prevent transpiration and they can store water inside them.

When your muscle cells do not get enough oxygen, fermentation can create?
Answer:
Your muscles are forced to work without enough oxygen. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce.
Explanation:
When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

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.

Two characteristics of most plants are a root system and a shoot system. Most of the structures in these systems are common to all plants; however, there are some variations. Which structure can sometimes be found as part of the shoot system? Stems leaves roots flowers
Answer:
stems, leaves, flowers
Explanation:
There are two parts in the plants ----
1. the shoot system
2. the root system
Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.
The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.

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.

Hope this helps!
According to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.
What is Community?A Community may be defined as a group of individuals belonging to different species living in the same area at a given time.
The individual is the unit of the population, while the population is the unit of evolution. This form of evolution is significantly required in order to construct a community where the different groups of individuals of different species are gathered in such a way that one depends on another.

RNA interference (RNAI) is a mechanism of gene regulation in eukaryotes. RNAI is initiated by ____, which leads to the ____ of specific genes.
Box 1:
single-stranded RNA
double-stranded RNA
double-stranded DNA
Box 2:
silencing
induction
expression
Answer:
double-stranded RNA; silencing
Explanation:
The RNAi mechanism is a natural process of gene silencing triggered by different small non-coding RNAs such as, for example, siRNAs, miRNAs and piRNAs. RNAi is a powerful technique to induce gene silencing in a sequence-specific manner. The delivery of exogenous double-stranded RNAs (dsRNAs) can be used to induce this evolutionarily conserved mechanism. The dsRNAs first bind to RNAi core components (Ago, Piwi proteins) and then target complementary mRNAs to induce their degradation.

What process is being used by the cell to move the molecules
The process that is being used by the cell to move the molecules is known as diffusion.
Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane. It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.
In conclusion, the correct option is Diffusion.

Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
