Answer:

A.

Explanation:

We exhale carbon dioxide and inhale oxygen.

Answer:

Gas exchange allows the body to replenish the oxygen and eliminate the carbon dioxide So the answer is A

Answer:

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.

The best demostration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.

Explanation:Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.  

When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.

Answer:

2. Each parent contributes only one allele for the ABO blood group to the offspring

Explanation:

Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.

Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.

Answer:

increase; decrease; increase; decrease

Explanation:

When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, an increase in predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with a consequent decrease in algae.

With the introduction of predatory fish, a decrease in the population of zooplankton-eating fish would occur due to predation by the newly introduced fishes. This will cause the population of zooplankton to thrive or increase.

Zooplanktons feed on algae. Hence, an increase in their population will put pressure on the alga in the ecosystem and cause a decrease in their population.

Answer:

The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.

Answer:

A pedigree chart is used to track inherited traits through generations (option C).

Explanation:

A pedigree chart is a graphical representation, similar to a family tree, showing specific traits present in parents, children and relatives. It is a diagram commonly used in genetics.

A certain phenotype, product of genetic traits, is represented in a pedigree chart by pre-established symbols, which is useful for tracking inherited traits through generations.

Answer:

This is because there may be one large producer or a small number of very large producers. For example, adult oak trees are extremely large and a single one may be home to hundreds of organisms. Thus, the number of organisms in the lower level of the pyramid of numbers will be less.

To Find :

The recombination frequency between these two mutations.

Solution :

Formula of calculating recombination frequency is :

[tex]R.F = \text{Number of mutations}\times \dfrac{\text{number of k plaques} \times D.F }{\text{Volume used}}\times \dfrac{Volume'}{\text{Number of B plaques} \times D.F' }}[/tex]

Putting all given values in above equation, we get :

[tex]R.F = \dfrac{2\times 400\times 0.2 \times 10^4}{16\times 0.1\times 10^8}\\\\R.F = 0.01[/tex]

Therefore, the recombination frequency between these two mutations is 0.01 or 1 %.

Given:

                     [tex]V'= 0.2[/tex]

The formula:

→ [tex]R.F = No. \ of \ mutations\times \frac{No. \ of \ k \ plaques\times D.F }{Volume}\times \frac{Volume'}{No. \ of \ B \ plaques\times D.F'}[/tex]

By putting the values in the above formula, we get

→         [tex]= \frac{2\times 400\times 0.2\times 10^4}{16\times 0.1\times 10^8}[/tex]

→         [tex]= \frac{160\times 10^4}{1.6\times 10^8}[/tex]

→         [tex]= 0.01[/tex]

Thus the solution above is the right approach.

Cell biology is the subdiscipline of biology that studies the basic unit of life, the cell. It deals with all aspects of the cell including cell anatomy, cell division  (mitosis and meiosis), and cell processes including cell respiration and cell death.

Explanation:

Answer:

1- Test tube with DNA sample is placed in machine

2- DNA sample is heated

3- DNA denatures

4- Taq polymerase initiates DNA synthesis

5- Double-stranded DNA is produced

Explanation:

The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).

Answer:Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ [tex]RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

⇒       [tex]=\sqrt{(3-(-2))^2+(4-4)^2}[/tex]

⇒       [tex]=\sqrt{(3+2)^2+(0)^2}[/tex]

⇒       [tex]=\sqrt{25}[/tex]

⇒       [tex]=5 \ units[/tex]

and,

⇒ [tex]ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

⇒       [tex]=\sqrt{(3-3)^2+(-1-4)^2}[/tex]

⇒       [tex]=\sqrt{0+(-5)^2}[/tex]

⇒       [tex]=5 \ units[/tex]

Now,

The total trail length will be:

= [tex]RS+ST[/tex]

= [tex]5+5[/tex]

= [tex]10 \ units[/tex]

Explanation:

Enzymes that work in the stomach must adjust to the unique environment by being able to function in an acidic environment.

One or more polypeptide chains of amino acids make up a big protein enzyme molecule. The unique protein folding patterns, which are crucial for enzyme specificity, are determined by the amino acid sequence.

Pepsin and rennin are the two primary enzymes found in gastric juice. While rennin coagulates the soluble milk protein, casein, into an insoluble curd, which is then attacked by pepsin, pepsin breaks down proteins into short polypeptide chains. Pepsin is produced by the chief cells of the stomach as pepsinogen, an inactive zymogen.

Explanation:

Genetics is the part of science managing the standards of variety and legacy in creatures and plants. The investigation of hereditary qualities gives us more prominent comprehension of how we can decide the probability of acquiring certain characteristics and clarifies and anticipate examples of legacy in family lines.

Each living life form is comprised of a wide range of qualities, or recognizing attributes, that make it a special person. Certain characteristics in plants and creatures may have characteristics that individuals need to advance.
