Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell

Answers

Answer 1

Explanation:

Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.

Answer 2

Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.

What is diffusion?

Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.

The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.

Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

Which is a difference between active and passive transport?
A. Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
B. Cells only carry out active transport when they need to move, while passive transport occurs constantly.

C. Active transport requires ATP, while passive transport does not.
D. Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.

Answers

if i am not mistaken , the answer is C .

Active transport really needs ATP to work , while passive transport doesn’t need ATP .

The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.

Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).

Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.

Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.

Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.

How many factors does a scientist want to differ between the experimental and control groups?

A) 2

B) 0

C) 1

D) 3

Answers

Answer:

C

Explanation:

The experimental and control group differ by only one factor for a scientist, and that is the independent variable.

A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.

The correct option is, therefore, C.

in what ways can overpopulation be beneficial to differential reproductive success?

Answers

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.

Answers

Answer and Explanation:

Petroleum and coal are fossil fuels.  The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.

Answers

Answer:

Pulled and wattled = 9/16

Pulled and no wattle = 3/16

horned and wattled = 3/16

horned and no wattle = 1/16

Explanation:

Pulled = P, Horned = p

Wattled = W, no wattle = w

Polled, wattle goats = P_W_

Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.

       PpWw    x    PpWw

Genotypes ratio of the offspring:

P_W_ - 9/16

P_ww - 3/16

ppW_ - 3/16

ppww - 1/16

Phenotype ratio of the offspring:

Pulled and wattled = 9/16

Pulled and no wattle = 3/16

horned and wattled = 3/16

horned and no wattle = 1/16

(See the attached image for the Punnet's square)

Some alleles of a gene are dominant to others masking the effect this other alleles.

The polled, or no horn, trait (P) is dominant to the horned (p) trait.

Having wattles (W) is dominant to not having wattles (w).

A breeder crosses a polled, wattled male goat with a polled, wattled female goat.

The phenotypic and genotypic ratios would be

Polled and wattled = P_W_      =  9/16Polled with no wattle = P_ww =  3/16horned and wattled = ppW_     =  3/16horned with no wattle = pwpw =  1/16

Parent genotype --- polled, wattled male and female goat -- P_W_

As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.

Hence, they are both heterozygotes with PpWw for the traits.

Parent genotypes:  PpWw             x      PpWw

                             PW Pw pW pw         PW Pw pW pw

                PW         Pw          pW         pw

14. a science student claims that a substitution mutation is less likely to affect gene function than an insertion or deletion mutation. use logical reasoning and evaluate this claim.

Answers

DNA functions in codons which are pairs of three amino acids. In substitution since one is taken out and replaced, only the codon that that acid would have been in is affected. With insertion or deletion every codon on is shifted due to the presence of a new amino acid

Because insertions and deletions produce a frame-shift that modifies the interpretation of following codons, they are frequently more detrimental than substitutions that modify only one amino acid.

What is a mutation?

A alteration in the DNA sequence of an organism is referred to as a mutation. Errors in the replication of DNA during the process of cell division, exposure to mutagens, or viral infections are all potential causes of mutations.

Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.

Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, as a result, alters the entire amino acid sequence that follows the mutation, insertions and deletions are typically more harmful than substitutions, in which only one amino acid is changed. This is because frame-shifts change the reading of subsequent codons.

Answer:

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
