Answer:
Free radical theory of aging.
Explanation:
Free radical theory of aging suggests that aging is the result of unstable oxygen molecules that cause damage to the structure of cells with age because cells accumulate free radical damage overtime and free radical is an atom with unpaired electron in it's outermost shell. It is associated with oxidative damage.
the free radical theory is only concerned with free radicals such as superoxide ( O2− ), but it also comprises of oxidative damage from other reactive oxygen species such as hydrogen peroxide (H2O2), or peroxynitrite (OONO−).
A bacterial genome is typically a single linear piece of DNA. multiple linear pieces of DNA. a linear RNA molecule. a single circular DNA molecule. multiple circular DNA molecules.
Answer:
The correct answer is Single Circular DNA Molecule.
Explanation:
A bacterial genome, which is the DNA that is found in bacteria collectively, is a double stranded circular DNA. So it has no start and end like double stranded helix DNA. The option D, which is "Single Circular DNA Molecule" is correct.

Enzymes only work with certain substrates. If a certain enzyme only works with a certain substrate, it is because the enzyme Group of answer choices has a particular shape that matches the substrate. can only reach that one substrate inside the cell. activates in response to chemicals from the substrate. is only found in organisms with that substrate.
Answer:
has a particular shape that matches the substrate
Explanation:
Enzymes are proteinous biological catalyst i.e. they speed up the rate of biochemical reactions in living systems. Like every other catalyst, enzymes reduce the activation energy of the reactions they are involved in without getting used up in the process.
Enzymes operate by binding to a substrate molecule i.e. the reactant and form a bond with them in order to synthesize a product. However, enzymes are substrate-specific i.e. they are very particular about the substrate they bind to. This property is due to the shape of the enzyme which matches a particular substrate.
Enzymes, like every other protein molecules, are made up of amino acid subunits, which are responsible for the shape that determines the specificity of the protein.

Discuss a natural resource in your region and describe how one of the approaches to natural resources management described in this section would be appropriate for that resource.
Answer:
My hometown has a reservoir that stores large amount of water. I believe that a community-based management approach would be appropriate for this resource. The people of the town rely on this resource for their livelihood, so they are motivated to protect this resource and use it in a sustainable way.
Other towns are not impacted by the use of this resource. Thus, higher-level government management is not required.
Explanation:
this is the plato answer
Water management refers to the process of planning, developing, distributing, and managing water resources to meet human needs and ensure sustainable use of water.
What is the reason of water management ?Effective water management is crucial to ensure that water resources are utilized efficiently and sustainably, and that there is enough water available to meet the needs of all users.
Some key aspects of water management include:Water conservation: Reducing water waste and promoting efficient use of water through measures such as improving irrigation systems, fixing leaks, and promoting water-efficient technologies.
Water allocation: Determining how much water is available and allocating it among competing uses such as agriculture, industry, and domestic use.
Water quality management: Ensuring that water is safe for human consumption and meets the necessary quality standards by monitoring and treating water supplies.
Watershed management: Managing the land area that drains into a particular water body to maintain the quality and quantity of water in the river, lake or aquifer.
Water infrastructure: Developing and maintaining infrastructure such as dams, reservoirs, pipelines, and treatment plants to store and transport water.
Water governance: Ensuring that water resources are managed fairly and transparently by establishing policies, regulations, and institutions that promote sustainable use and protect the rights of all users.

Explanation:
The two thyroid hormones, thyroxine and triiodothyronine, have complementary effects in which they decrease the rate of cellular metabolism and oxygen consumption in almost every cell in the body.
a. True
b. False
Answer:
False
Explanation:
The thyroid gland secrete two thyroid hormones called thyroxine and triiodothyronine. Thyroxine is the in active form which is later converted to the active form triiodothyronine by kidneys and livers. The two hormones function by increasing the metabolic activities of tissues. They increase the body heat production which in turn increase oxygen consumption and ATP hydrolysis because they burn body fat thereby increasing energy production and increasing basal metabolic rate. They regulate body temperature.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)
Answer:
W = b0 + 2381 b1
Explanation:
First of all, you need to understand that in the formula shown above, the "W" represents the weight in tones. The "b0 + b1" are the constants, "D" is the diameter of the tree that must be presented in centimeters and the "H" is the height of the tree in feet.
As shown above, the circumference of the pine is 14 inches, but we know that the circumference is equal to 2πr, in this case, we will use the value 22/7.
I understand the factors above we will have the formula:
14 = 2 (7/22) × r
14 = (44/7) × r
r = 14 × 7/44 = 2.23 inches
So the diameter = 2r = 4.45 inches
Now we will replace the formula W = b0 + b1 (D2H).
W = b0 + b1 (4.45 ^ 2 * 120)
W = b0 + 2381 b1
To solve the rest we would need the values of b0 and b1, which we don't have. For that reason, the answer would be ended in this way.

Answer:
hope it helped u
plzzz mark as brainliest.
Explanation:
Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.
Mutations that cause the altered codon to produce an amino acid with similar functionality (e.g. a mutation producing leucine instead of isoleucine) are often classified as silent; if the properties of the amino acid are conserved, this mutation does not usually significantly affect protein function.
Answer:
Missense mutation

A ship is at anchor. Over its side hangs a rope ladder with rungs a foot apart. The
tide rises at the rate of 8 inches per hour. At the end of 6 hours, how much of the
rope ladder will remain above the water, assuming that 8 feet were above the
water when the tide began to rise?
Answer:
At the end of 6 hours, 6 feet of the ladder remained above water
Explanation:
we are given the following:
change in tide = 8 inches per hour
1 hour = 8 inches
∴ 6 hours = 8 × 6 = 48 inches
Now, since the length of the ladder is measured in foot, let us convert the rate of tide rising to foot.
12 inches = 1 foot
dividing both sides by 12:
[tex]1\ inch=\frac{1}{12}\ feet\\ \therefore 48\ inches\ =\ 48\ \times \frac{1}{12}\\ =\frac{48}{12}\\ = 2 feet[/tex]
Therefore, after 6 hours, the tide rises by 2 feet.
Next, we are told that the rope ladder at the beginning was 8 feet, hence the length remaining above water after 6 hours of the rising of the tide is calculated as follows:
= 8 feet above water
height of tide = 2 feet = amount submerged in water
∴ length above water = (ladder before rising of the tide) - (amount submerged in water)
length above water = 8 - 2 = 6 feet
Therefore at the end of 6 hours, 6 feet of the ladder remained above water

how does a human and scuba gear interact
Answer:
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus, or scuba gear, which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers.

The independent variable is the variable that is changed in an experiment. a True b False
True.
Explanation:
An independent variable is what is changed by the scientist experimenting, or you. An easy way to remember this is that independent starts with an "I", which "I" am the one that manipulates the variable. A good experiment only has one independent variable.
A dependent variable is the data of the experiment. This could be the impact a drug has on individuals, how much a plant has grown, test scores of students, etc. What is measured at the end of an experiment is the dependent variable.
A control variable is something that is stayed constant throughout the experiment. This could be the amount of water, type of soil, amount of light, the color of light, etc. These things are not changed.
