Sand cats eat primarily small rodents, occasionally hares, birds, spiders, insects and reptiles. They are fearless snake hunters—their prey can include venomous vipers and other snakes. Living in a relatively desolate habitat, sand cats are opportunistic feeders out of necessity.

Answer:

Individuals who are heterozygous for co-dominant traits show in their phenotype both traits, without mixing.

Explanation:

Codominance is a type of inheritance that does not follow the rules of Mendelian inheritance, characterized by the absence of recessive traits and two different alleles for a character that behave as dominant.

Heterozygous individuals can be observed in codominance that show two different characteristics in their phenotype, without mixing, such as cattle with spotted skin or two colored flowers.

Answer:

Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.

The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.

Explanation:

The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.

The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.

When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.

The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.

Mitochondria are cell organelles that generate the maximum of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).

The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).

The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M

This question is incomplete as it lacks options, the options are:

A) a single variable

B) multiple variables

C) the hypothesis

D) scientific observations

The answer is A

Explanation:

An experiment is conducted to solve a particular problem or find answers to a given scientific question. In an experiment, which usually consists of variables, only A SINGLE VARIABLE is tested at once.

This means that the effect of a variable called INDEPENDENT VARIABLE is tested at a time. The independent variable is the variable that is changed or manipulated in an experiment. This means that only a SINGLE VARIABLE can be changed at at time in an an appropriate design experiment.

Answer:

Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body. The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. If you were to lay out all the blood vessels of the body in a line, they would stretch for nearly 60,000 miles. That’s enough to circle the earth almost three times!

1. The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries

The different types of blood vessels and their layers

Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. These layers surround the lumen, the hollow interior through which blood flows.

2. Oxygenated Blood Flows Away from the Heart Through Arteries

The major arteries and branches of the body

The left ventricle of the heart pumps oxygenated blood into the aorta. From there, blood passes through major arteries, which branch into muscular arteries and then microscopic arterioles. The arterioles branch into the capillary networks that supply tissues with oxygen and nutrients. The walls of arteries are thicker than the walls of veins, with more smooth muscle and elastic tissue. This structure allows arteries to dilate as blood pumps through them.

3. Veins Carry Blood Back Toward the Heart

The superior and inferior vena cava

After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae. Vein walls are thinner and less elastic than artery walls. The pressure pushing blood through them is not as great. In fact, there are valves within the lumen of veins to prevent the backflow of blood.

4. Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries

Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. Elsewhere in the body, oxygen and other nutrients diffuse from blood in the capillaries to the tissues they supply. The capillaries absorb carbon dioxide and other waste products from the tissues and then flow the deoxygenated blood into the veins.

5. The Constant Pumping of the Heart Maintains Blood Pressure and Supply Throughout the Body

Click to play an animation of blood pressure measurement

The blood moving through the circulatory system puts pressure on the walls of the blood vessels. Blood pressure results from the blood flow force generated by the pumping heart and the resistance of the blood vessel walls. When the heart contracts, it pumps blood out through the arteries. The blood pushes against the vessel walls and flows faster under this high pressure. When the ventricles relax, the vessel walls push back against the decreased force. Blood flow slows down under this low pressure.

Answer:

Tissue engineering evolved from the field of biomaterials development and refers to the practice of combining scaffolds, cells, and biologically active molecules into functional tissues. The goal of tissue engineering is to assemble functional constructs that restore, maintain, or improve damaged tissues or whole organs. Artificial skin and cartilage are examples of engineered tissues that have been approved by the FDA; however, currently they have limited use in human patients.  

Regenerative medicine is a broad field that includes tissue engineering but also incorporates research on self-healing – where the body uses its own systems, sometimes with help foreign biological material to recreate cells and rebuild tissues and organs.  The terms “tissue engineering” and “regenerative medicine” have become largely interchangeable, as the field hopes to focus on cures instead of treatments for complex, often chronic, diseases.

Explanation:

The difference in the size of both rats are due to genetic and environmental because rats of both location increased in size which eats a lot of food as compared to those rats which eats balanced diet. This is due to the environment while on the the other hand, due to difference in genetics, New York rats grew larger than California rats of your friend which eats large number of food. So we can say that both genetic and environmental factors affect the rats size.

Explanation:

X-linked disorders result from mutated genes on the X chromosome. Males, who have only one X chromosome (i.e., they are hemizygous), will fully express an X-linked disorder. On the other hand, females, who have two X chromosomes, will be carriers of the defect in the majority of cases, and so they are usually asymptomatic.

Answer: Overgrazing, overfishing, and forest fires

Explanation:

Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.

According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.

The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.

Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.  

Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

Answer:

b. any base pair can pair to any other base

Explanation:

Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.  

• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.  

• The majority of the DNA is present within the nucleus of the cell.

• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.  

• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.  

• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate  and sugar.  

• Together, a phosphate, base, and sugar are known as a nucleotide.
