Answer: c. Senescence begins once body structures reach maximum capacity and efficiency
Explanation: Senescence is simply ‘growing old’. Aging sets in at the time when physical development is complete - when a person reaches their ‘prime’. After that a person is ‘past their prime’ which is the subjective recognition of the on set of gradual deterioration. The biological rationale is that the purpose of life is to survive to reproductive age and to reproduce, and in some species to assist progeny to survive to reproductive age. Beyond that, survival has limited value.
An analogy is the length of an elephant’s trunk. It is as long as it needs to be, determined by natural selection, but no longer than it needs to be for optimum efficiency, again determined by natural selection.
what is the primary difference between diffusion and osmosis
Long answer here!
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.
Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.
On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.
Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

Which statement describes the epiphyseal plate? It is where flat bones are actively growing. It is where old bone cells are being remodeled. It is where cartilage cells are being turned into bone cells. It is where the bones in a baby's skull are growing together.
Answer:
The correct answer is - It is where cartilage cells are being turned into bone cells.
Explanation:
The epiphyseal plate is a plate of cartilage that is found at the end of each long bone, is a location for the longitudinal growth of the bones that are responsible for the height or long bone growth of an individual.
It is the site that is responsible for the formation of the cartilage bones by the process of proliferation of cells and hypertrophy of the cell which is then turned into the bones. This change takes place due to calcification, degradation, and replacement by osseous tissues.
Answer: c.) It is where cartilage cells are being turned into bone cells.
Explanation: The epiphyseal plate is also known as the growth plate. This is the site of bone elongation, where cartilage cells are being converted to bone cells

Coral needs sunlight to grow. True or false identify if it is false.
Answer:
Yes ,corals depend on the zooxanthellae (algae) that grow inside of them for oxygen and other things, and since these algae needs sunlight to survive, corals also need sunlight to survive.
Answer:
True
Explanation:
Corals need to grow in shallow water where sunlight can reach them. Corals depend on the zooxanthellae (algae) that grow inside of them for oxygen and other things, and since these algae needs sunlight to survive, corals also need sunlight to survive.

A rich variety of genetic material in an ecosystem will:
1. reduce the biodiversity of the ecosystem
2. decrease the carrying capacity of the ecosystem
3. reduce the likelihood of future medical discoveries
4. increase the chances that some organisms will survive change
A rich variety of genetic material in an ecosystem will increase the chances that some organisms will survive change.
What is an ecosystem?An ecosystem contains all the organisms and the biological environment (which contain abiotic and biotic factors ) with which they show interaction.
These biotic and abiotic components are related concurrently through nutrient and water cycles and energy discharges.
Energy joins the procedure through photosynthesis and is interspersed into plant tissue.
Thus, option 4 increases the chances that some organisms will survive change is correct.

What are the chemicals for the two strands of nucleotides
Answer fast pleaseee
The chemical structure of DNA and its nucleotides The DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure and orientation of the two strands are important to understanding DNA replication.

Saponification Select one: a. is a hydrolysis reaction. b. results in the production of triglycerides. c. is used to store energy for later use. d. is a reaction found in plant metabolism.
Answer:
A) hydrolysis reaction
Explanation:
hydrolysis can be explained as a chemical process whereby molecules of water is been added to a substance, and in most reaction the substance and the water molecules split to two part as a result of the addition, and there would be gaining bof hydrogen ion by fragment of the parent molecule. An example of this is saponification.
Saponification can be defined as process of converting oil fat as well as lipid to soap and alcohol through heating using aqueous alkali. Common aqueous alkali that can be used is NaOH. Soap are regarded as salt of fatty acid. Reaction between Ethanoic acid and alcohols is an example of a saponification
Here is soap chemical formula
CH3(CH2)14COO− Na+
Answer: The correct option is A ( is a hydrolysis reaction).
Explanation:
Saponification is the alkaline hydrolysis ( using sodium hydroxide or potassium hydroxide) of fats and oil. It is commonly used for making of soaps which are used for washing and cleaning.
The process is a hydrolysis reaction because there is splitting of ester linkage bonds of triglycerides and addition of hydroxyl group from a hydroxide. This process leads to the production of alkaline salts of long chain fatty acids(soaps). This can be summarised below
Triglycerides (fats&oil) + base( NaOH)
-------> Soap + Alcohol

Why do cells need to carry out cellular respiration?
What is the relationship between respiration and cellular respiration?
Answer:
Through a chemical process called cellular respiration. As you know, respiration is the process of breathing. Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the oxygen your cells need for cellular respiration.

How would a small, uncharged lipid move across the cell membrane?
o through simple diffusion, down the concentration gradient
O through simple diffusion, against the concentration gradient
o through facilitated diffusion, down the concentration gradient
O through facilitated diffusion, against the concentration gradient
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
