write paragraph about digestion of food in brief​

Answers

Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

according to wikipedia!

Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen

Answers

Answer:

Explanation:

Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily.  These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.

Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.

Scientists have been studying the size of three populations in a river in Ireland. In this ecosystem, pike (a type of big fish), and perch eat snails. The data showed that all three populations were stable. Then the snail population increased suddenly. What will likely happen to the size of the perch population as a result? The size of the perch population will...

Options:

A. Stay the same. The size of it's consumer population did not change, so the number of deaths in the perch population did not change. There will be the same number of births and deaths in the perch population.

B. Decrease. The larger snail population will take more energy storage molecules from the ecosystem, leaving fewer available for the perch population. This will lead to more deaths than births in the perch population.

C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.

D. Increase. An increase in any population within an ecosystem will lead to an increase in the sizes of all other populations in the ecosystem.

Answers

Answer:

C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.

How do somatic and Inherited mutations differ?
O A. Somatic mutations exist in all cells in the body and Inherited mutations only exist In the cell type that mutated.
O B. Inherlted mutations exist in all cells in the body and somatic mutations only exist In the cell type that mutated.
O C. Somatic mutations only affect males and inherited mutations affect any gender.
O D. Inherited mutations only affect males and somatic mutations affect any gender.

Answers

The right option is; B. Inherited mutations exist in all cells in the body and somatic mutations only exist in the cell type that mutated.
Inherited mutations are gene mutations that exist in almost every cell in the body throughout an individual’s life. Inherited mutations are inherited from a parent and can also be transmitted. They are also called germline mutations because they exist in the parent’s egg or sperm cells (gametes).
Somatic mutations are gene mutations that exist in only certain cell types that are mutated, not in every cell in the body and it take place at some time during an individual’s life. Somatic mutations are not inherited and cannot be passed. They are caused due to environmental factors (such as cigarette smoke or ultraviolet (UV) radiation) or due to error during DNA replication.

what are some of the actions that the somatic nervous system does?

Answers

Mark Brainliest please

Answer

It regulates voluntary activities.
It relays information to and from skin and skeletal muscles

Explanation

The somatic nervous system is part of the peripheral nervous system (part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs). It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).

The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).

The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat

While alive, an organism absorbs (radioactive) carbon 14 at such a rate that the proportion of carbon 14 in the organism remains at a known constant level. When it dies, it no longer absorbs carbon 14, so its proportion of carbon 14 begins to decrease. The half-life of carbon 14 is 5,600 years. A human skeleton is discovered whose level of carbon 14 is 15% that of a living human. To the nearest 100 years, how long ago did the person die

Answers

Answer:

The person has been dead for approximately 15,300 years

Explanation:

Available data:

The half-life of carbon 14 is 5,600 yearsThe human skeleton level of carbon 14 is 15% that of a living human

To answer this question we can make use of the following equation

Ln (C14T₁/C14 T₀) = - λ T₁

Where,

C14 T₀ ⇒ Amount of carbon in a living body at time 0 = 100%C14T₁ ⇒ Amount of carbon in the dead body at time 1 = 15% λ ⇒ radioactive decay constant = (Ln2)/T₀,₅T₀,₅ ⇒ The half-life of carbon 14 = 5600 yearsT₀ = 0T₁ = ???

Let us first calculate the radioactive decay constant.

λ = (Ln2)/T₀,₅

λ = 0.693/5600

λ = 0.000123

Now, let us calculate the first term in the equation

Ln (C14T₁/C14 T₀) = Ln (15%/100%) = Ln 0.15 = - 1.89

Finally, let us replace the terms, clear the equation, and calculate the value of T₁.

Ln (C14T₁/C14 T₀) = - λ T₁

- 1.89 = - 0.000123 x T₁

T₁ = - 1.89 / - 0.000123

T₁ = 15,365 years

The person has been dead for approximately 15,300 years

what is cyclin dependent kinase?​

Answers

Answer:

please mark as brainliest answer as it will also give you 3 points

Explanation:

Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.[1] They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene.[1][2] CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain.[1] By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27. CDKs phosphorylate their substrates on serines and threonines, so they are serine-threonine kinases.[1] The consensus sequence for the phosphorylation site in the amino acid sequence of a CDK substrate is [S/T*]PX[K/R], where S/T* is the phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine.[1]
