Final answer:

The molecules in the food consumed by a squirrel are converted to energy and other types of molecules through the process of cellular respiration.

Explanation:

When a squirrel consumes acorns for food, the molecules in the food are not eliminated completely, nor are they destroyed in the animal's body. Instead, these molecules undergo a biochemical process known as cellular respiration. During cellular respiration, the organic molecules originally produced by plants, like sugars, are converted into energy that the squirrel's body can use for various life processes. Additionally, these molecules are transformed into other types of molecules that are necessary for the squirrel's growth and maintenance. So the correct answer is B. The molecules get converted to energy and other types of molecules.

Answer:

Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.

One monomer is one nucleotide which further consists of three parts:

1: Nitrogenous base

2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)

3: Phosphate group

Explanation:

If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.

You can see a better representation in attached figure.

Hope it help!

In a single strand of nucleic acid, the monomers (nucleotides) are held together by phosphodiester bonds. These create a sugar-phosphate backbone with protruding nucleotide bases. The bases can pair with others to form a double helix structure via weaker hydrogen bonds.

The monomers of a single strand of nucleic acid, known as nucleotides, are held together in a chain by phosphodiester bonds. These bonds occur between the 5' phosphate group of one nucleotide and the 3' hydroxyl group of the next nucleotide, linking them together to form a long polymer or chain. This bonding creates a sugar-phosphate backbone for each single strand of DNA, where the nucleotide bases protrude.

Various nucleotides are used in this process, including adenine, thymine, cytosine, and guanine in DNA, and these form a double helix structure when two such strands are attached at their protruding bases via millions of hydrogen bonds. This structure can easily unzip down the middle, due to the relatively weaker hydrogen bonds compared to the strong covalent bonds in the phosphodiester bonds, allowing both strands to function as templates for replication.

More co2 which can cause “holes” in the earths atmosphere causing the suns radiation to come through.

The correct answer is C)  70/x.

To calculate doubling time, rule of 70 formula is used.   For this the annual growth rate of the population is required. In this question growth rate is given x.  Thus, doubling time = 70/ growth rate.

Therefore, doubling time = 70/x.

Answer:

Option C

Explanation:

Rate of increase in a population is generally written as net population increase in a unit time.

Here "X" represents the growth rate of population of wolves.

Let us assume that X is equal to [tex]23[/tex] wolves per month.

This means that 23 wolves are added every month to the wolves population.

Suppose if we have to derive the time in which the wolves population will increase to any number let us say "Y"

Then , time required will be equal to

[tex]\frac{Y}{X}[/tex]

That means X will be denominator in a mathematical expression.

Thus, option C is correct

If Glycolysis stopped happening in the cell, the cell would not likely produce ATP molecules and in the same time, the Krebs cycle will not function without it. It is because glycolysis is the one responsible for enzyme breakdown and releasing energy which is important for krebs cycle and for atp molecules to be produced.

Glycolysis occurs in nearly all living cells or organisms.

Glucose provides most of the energy used/produced by cells.

Glucose is the principal source and is mainly used in glycolysis for the production of energy for cellular metabolism.

Glycosis helps to process glucose to pyruvate in many cellular respiration procedures.

In the presence of oxygen, one glucose molecule has the energy to make up to 38 ATP.

The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place.

All these processes take place under the cellular function of cellular respiration.

Thus, glycolysis is the one responsible for enzyme breakdown and releasing energy which is important for Krebs cycle and for atp molecules to be produced.

It has more similarity to fossils in layer A than layer D.

Answer:

If the rock samples obtained are in the order A-B-C-D from top to the bottom then fossil found in layer B has more similarity to fossil in layer A than layer D.

Explanation:

To estimate the age of fossil we try to determine the age of rock from where the fossil was obtained. The deeper the rock layer, older the fossil would be. Here in the question the most deepest layer of rock is D which means the fossil remains obtained here would be the oldest and can be considered as the ancestor of other the fossils obtained in the layers above it.

The top most layer is A, which is the most recent layer and would contain fossil remains of most recently fossilized animal. Fossils obtained from adjacent layers are expected to have more similarities than the ones obtained from distant layers. Since rock layer B is more closer to A, it will have the fossils with more similarities to fossils in layer A than in layer D.

the answer is conduction - the transfer of heat to an object through contact

The world wouldn't be livable, that is correct.

The statement that is true is the third statement: Layer A is the outer core and Layer B is the inner core.

Answer:

Option C, Layer A is the outer core and Layer B is the inner core.

Explanation:

The core of earth consists of two parts - outer core and inner core

The inner core of earth is made up of iron which exits at a high temperature equivalent to temperature of sun. The pressure at this layer is extremely high and thus the metal in this part of earth's core does not convert into liquid.  

While the outer core is made up of iron, nickel and other metals (in trace amount). As the pressure in this part of earth’s core is comparatively lower than that of inner core ,the metals exists in fluid form.

Thus, option C is correct

Option (C)

Explanation:

The magma when it comes out to the surface from the greater depth, the magma gets crystallized having the gold in it. These rocks sometimes alter into metamorphic rock due to the extreme pressure-temperature condition. These rocks are affected by the water as it flows over them and over a due course of time, it weathers and erodes the minerals and is carried to some other place. This process of erosion and deposition of minerals is known as the placer deposits.

Thus, Gold is one type of mineral that is distributed by this type of sedimentary process.

By capturing the pollen on their feet as they land on each new plant

Bees pollinate by collecting pollen or nectar from flowers, which sticks to their fuzzy bodies and gets transferred to other flowers as they move from one to another, assisting in the reproduction of many plants.

Bees, particularly species like bumblebees and honeybees, play a crucial role in pollination, which is vital for many garden plants and commercial fruit trees. As bees cannot perceive the color red, they are attracted to flowers with hues of blue, yellow, and other colors. These flowers typically have a tubular shape, bright colors, a pleasant aroma, and a nectar guide to efficiently direct bees to the center. The process begins when a bee lands on a flower to collect energy-rich pollen or nectar, essential for their sustenance and energy needs. When the bee enters the flower, the pollen adheres to its fuzzy body. The next time the bee visits another flower, some of this pollen is transferred to the second flower, resulting in pollination. However, a worrying trend has emerged with the declining population of honeybees, which could have dire consequences for pollination and, consequently, food production.

The correct answer is A. Cells

In living things, whether it is microscopic Amoeba, composed of one cell or big elephant made of many cells, a cell is the basic or fundamental unit. It is the smallest unit of a living thing. Thus, cells are the building blocks of all organisms. A cell perform all the life processes in unicellular organisms, whereas in multicellular organisms, they grouped into tissues to carryout functions.

Of the following given choices;

Crossing over occurs in metaphase and leads to variation.

Sister chromatids separate in anaphase 2.

Homologous pairs randomly separate in anaphase I.

Non-sister homologs break off and reform on different chromosomes.

The answer is; Homologous pairs randomly separate in anaphase I.

Particular genes, as Medel discovered, were inherited independently from one another while others were inherited together (linked genes).  This it was determined that this independence of inheritance of particular genes alleles is due to their location on different chromosomes of the homologous pair. When the sister chromosomes separate during anaphase I of meiosis, the different genes alleles go to separate daughter cells.

Explanation:

Let's talk about available options and how can they be true or false:

If we talk about option A, it says that radioactive materials cause the addition of methane in ground. As we know that methane is a gas that is present in the atmosphere since its lighter nature. Therefore, the pollution due to methane seeping into the ground do not makes a reasonable cause for pollution.

If we talk about option B, it says that Burning fossil fuels causes water pollution, as we know that burning of fossil fuels is a serious cause of air pollution because it increases the amount of harmful gases in the air. But in option, it is mentioned that fossil fuels cause water pollution which again is not a reasonable cause.

If we talk about option C, it says that deforestation causes acid rain by decreasing carbon dioxide (CO2) in the atmosphere. However in actual deforestation in the cause of enhanced amount of CO2 emissions which in turn cause the acid rainfall. Therefore, the option is clearly wrong.

If we talk about option D, it says that aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3). As we know that aerosol sprays are the leading cause of damaging ozone layer and causing big holes in it therefore there is a lot of focus now adays by environmentalists to minimize their usage.

Hence D is correct option.
