Your cells have a unique MHC (major histocompatibility complex). Directions for producing MHCs come from _________________.


A. the helper T-cells

B. the thymus

C. inherited DNA

D. the bone marrow

Answers

Answer 1
C. inherited DNA :)))
Answer 2

The directions for generating MHC comes from the option c. inherited DNA. hence, the option c is correct.

What is MHC?

The full form is a major histocompatibility complex. It is the genes group that have the proteins code that should be founded on the cell surface which helped the immune system, that recorded in the foreign substance.

So at the time of directing, it produced MHC that came from inherited DNA.

hence, the option c is correct.

Answers

Answer:

  lipid synthesis

  protein modification

  intracellular transport

This is if you have to pick more than one

Explanation:

Because i got it wrong

The most important function of the endoplasmic reticulum is intracellular transport within the cell but ER also performs other functions.

What is intracellular transport?

The Endoplasmic Reticulum transports nutrients from one part of the cell to the other within the cell.

What is Endoplasmic reticulum?

The endoplasmic reticulum (ER) is a continuous membrane structure in eukaryotic cells that forms a series of flattened sacs inside the cytoplasm.

There are two forms of ER that are commonly found:-Rough ER, which has  ribosomes embedded within its structure, giving it a rough appearanceSmooth ER, which lacks these ribosomes and hence appears smooth.

The endoplasmic reticulum (ER) plays an essential role in protein synthesis, folding, modification, and intracellular transport.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.​

Answers

Answer:

All the statements are true and the correct option is;

D. All of these are true

Explanation:

Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities

An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system

An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity

Therefore all the statements are true.

which two adaptations of herbivorous enables them to digest cellulose​

Answers

Answer:

Cellulose Digestion in Herbivores

By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.

Explanation:

Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.

How does herbivorous digest cellulose​?

Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.

Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.

Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.

Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose​.

What is Transcription?

The process in which  information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.

The  enzyme responsible for transcription is RNA polymerase.

Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins.

Initiation, Elongation, and termination are the three steps of transcription.

Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors.

Enhancer and promoter sequences are the  DNA sequences on which transcription factors attach to initiate the transcription process by directing  RNA polymerase to the correct transcription site.

The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

What does it mean to die of "natural causes" or to die of "old age"?

Answers

Explanation:ya que el cuerpo se dessasta por  estar en funsionamieto pormucho tiempoc

Logically speaking, dying of “natural causes” means dying from diseases such as a stroke, heart disease, and other illnesses are the most common ones. Although, not all things are natural causes of death like car accidents.

On the other hand, dying of “old age” is quite similar. It just means someone who is old died from a disease. You can’t actually die of old age. Older people just have a higher chance of getting illnesses than younger people, and possibly dying from it.

Explanation:

Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.

Answers

Answer:

Explanation:

Answer:

C. increases genetic diversity

Explanation:

First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

Answers

Answer:

C) exponential growth​

In the given figure, exponential growth curve is pictured.

What is exponential growth?

It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:

Lag phaseExponential phaseStationary phaseDeath phase

In the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.

In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.

Thus, the pattern of growth demonstrated in the given figure is exponential growth.
