How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?

Answers

Explanation:

How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?

The water that sea otters live in is chilly, ranging from 35 to 60 degrees Fahrenheit—much too cold for humans. Otters don't have blubber to keep them warm like other marine mammals. Instead, they rely on their thick fur coat to maintain a constant body temperature of 100 degrees Fahrenheit.

What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive

Answers

Answer: Polygenic recessive

Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.

This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

What is Polygenic inheritance?

Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.

Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.

Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

Why is it important for DNA to remain in the nucleus?

Answers

DNA cannot leave the nucleus because that would risk it getting damaged.
The most important function of the nucleus is to store the cell's genetic information in the form of DNA. DNA holds the instructions for how the cell should work. DNA stands for deoxyribonucleic acid. The molecules of DNA are organized into special structures called chromosomes. Sections of DNA are called genes which hold hereditary information such as eye color and height. You can go here to learn more about DNA and chromosomes.

______ plants are important in fixing nitrogen.

a. Legume

b. Berry

c. Nut

d. Poisonous

Answers

Answer:

A

Explanation:

Legume plants are important in fixing nitrogen. Therefore, the correct option is A.

Beans, peas, lentils and clover are examples of leguminous plants that are important for nitrogen fixation. They co-exist well with rhizobia, a type of bacteria that fix nitrogen. These bacteria live in nodules on the roots of legumes and use a process called nitrogen fixation to convert atmospheric nitrogen into a form that plants can use.

Legumes can obtain substantial amounts of nitrogen, an important nutrient for plant growth, without being entirely dependent on soil nitrogen, because of their ability to fix nitrogen. Legumes play an important role in agriculture and ecosystems, by adding nitrogen to the soil and increasing its fertility. Legumes are valuable crops because of their high protein content as well as their ability to improve soil health by fixing nitrogen.

Therefore, the correct option is A.

phenotype?

Answers

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.

D) bind to sequences just after the start site of transcription.

Answers

Answer:

B

Explanation:

The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.

Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.

The correct option is, therefore, B.

Describe as you travel through the different types of blood vessels (capillaries, arteries, and veins) as you make your journey through the different types of circulation (pulmonary/lungs, coronary/heart, and systemic/body) and reach the cells of the body.

Answers

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

Click to play an animation of blood flow through 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.

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.

Answers

Complete question:

Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.

All proteins will show the same degree of divergence because they are modified with the same rate of evolution.    All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.

Answer:

3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.

4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.

Explanation:

All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE.  All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE  All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.    

In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.

The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.

In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.

Answers

Answer:

Explanation:

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is decreased when adenosine triphosphate (ATP) levels rise because the molecule adenosine triphosphate (ATP) binds to an allosteric site on the enzyme and acts as a direct inhibitor. When adenosine triphosphate (ATP) levels fall, AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular adenosine triphosphate (ATP), so that this is an example of a negative feedback loop.

What is an aerobic respiration?

An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.

This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.

What is an enzyme?

An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.

Factors that affects an enzyme

There are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

The logarithmic concentration of hydrogen (pH).Temperature.Cofactors.Allosteric inhibitors.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​

Answers

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
