the DNA is tightly wrapped around histone proteins in a chromosome why is this packaging necessary?
1. Because the dna molecules will down without it .
2. Because the dna molecules will dissolve in cell water .
3.) because the long dna will fit inside the cell.
4.) because the dna needs to attach itself to support .

Answers

Answer:

3.) because the long dna will not fit inside the cell.

Explanation:

This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).

The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.

What are Darwin's Finches?

Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.

These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.

The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.

Which of the following is an intrusive igneous body?
O A. Stock
O B. Stope
O c. Magma Chamber
O D. Aphanite

Answers

Answer:

D. Aphanite

Explanation:

A.P.E.X

An invasive igneous body is aphanite. Thus, the correct option is D.

What are Aphanite rocks?

Aphanite's are igneous rocks that were formed by rapid cooling in a volcanic or hypabyssal setting and are so finely grained that their individual mineral crystals cannot be seen with the unaided eye.

Very fine-grained, crystalline fabrics called aphanitic minerals are created when a magma solidifies in reaction to an exceptionally rapid loss of heat and dissolved gases. They are characterized by grains that are too small to be recognized without a petrological microscope.

Large crystals are known to be present in certain specific igneous rocks. The crystals in this type of rock are approximately the same size. Compared to aphanitic rock, which is known to have rocks with finer grain sizes.

So, the correct option is D.

Name 4 ways that different types of disease can interact to make a person ill.

Answers

Answer:

Modes of transmission or means of transmission  is defined as the movement or transmission of pathogen from infected person or any reservoir to other person.

4 ways or modes of transmission of diseases include:

Contact (direct and/or indirect) -  Direct contact include physical relation between infected person or susceptible person such as kissing, sexual contact or transfer of oral secretion. Diseases caused by direct contact include small pox, pink eye and hepatitis a and B. Indirect contact include transmission of diseases form infected    person to susceptible person through a infected surface such as infected needle.Droplet: water droplet coming out of the mouth, perspiration or other open parts of the body carries pathogens to susceptible person. sneezing and coughing are most common of droplet ways through which diseases spread.Airborne: Some of the diseases are spread through means of air such as  chickenpox virus,  norovirus, measles morbillivirus, Mycobacterium tuberculosis and influenza virus et-cetra.Vector: Vectors are defined as an organism that carries disease causing pathogens from infected person to other host body. Fleas or other insects are example of vectors.

Hence, 4 ways that different types of disease transmission that can make a person ill are droplet, Contact (direct and/or indirect), vectors and airborne.

why can AIDS be classified as both an infectious disease and an immune system disorder ?

Answers

Answer:

Because AIDS can not only be passed from person to person but it can also affect your immune system in ways other infections diseases can not.

Explanation:

for example: type 1 diabetes is an auto-immune disorder and can not be passed on by bodily fluids. chlamydia is an infectious disease that can be passed on by bodily fluids.

AIDS is an auto immune disorder because it affects the immune system in the same ways that other auto-immune disorders do. this being so it can all so be found in the blood and passed on like an infection where as auto-immune disorders normally dont live in a persons blood.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: Osmosis, because energy is being used to move molecules with the concentration gradient. Active transport, because energy is being used to move molecules against the concentration gradient. Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

Answers

Answer:

Active transport, because energy is being used to move molecules against the concentration gradient.

Explanation:

This picture shows active transport. That just means that energy is being used (in this case, ATP) to move molecules against their gradient (meaning, from low to high concentration). Molecules "naturally" diffuse from high-->low concentration, so to move in the opposite direction requires energy input. You can tell this because there are only 2 molecules on the top side of the membrane, but on the bottom side there are 13.

Why not A: This is not necessarily water, as in osmosis, and it's not going with the gradient.

Why not C: This is not facilitated diffusion, because molecules are going against, not with, their concentration gradient.

The description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

WHAT IS ACTIVE TRANSPORT:Active transport is a type of transport that requires the input of energy in form of ATP. This is because the movement of molecules is against a concentration gradient.

According to the diagram in this question, molecules are being moved into the cell with an input of ATP (energy).

Therefore, the description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green
algae-living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its
photosynthetic activity from Elysia chlorotica, the sea slug that's considered to be a photosynthesizing animal?
CA In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only
during the immature juvenile stage of the slugs life cycle.
OC Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from
algae into its cells.
D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a
photosynthesizing organism only when it requires food.

Explanation:

It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.

What is water sterilization ?

It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.

An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.

Algae feed on nutrients, growing, spreading  and turning out the water green. Algae blooms smells bad, blocks sunlight and even releases out  chemicals in certain cases.

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.

Answers

Answer:

There are many reasons to get an influenza (flu) vaccine each year.

Flu vaccination can keep you from getting sick with flu.

Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.

Flu vaccination is an important preventive tool for people with chronic health conditions.

Flu vaccination helps protect women during and after pregnancy.

Flu vaccine can be life-saving in children.

Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.

Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.

Explanation:

Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.

Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.

What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."
