Answer:

Question 1: B the food web

They are all connected because they all depend on one another in order to survive.

Question 2: C. Dirt, water, pebbles, worms, and beans seeds

contains a living habitat, or ecosytem. This habitat might include plants, fungi, lichens, isopods (such as pill bugs), beetles, spiders, earthworms, amphibians (such as salamanders), reptiles (such as turtles), crickets, and more. Before you start: Having a terrarium is a responsibility.

Question 3: B. Grass

Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

Pickles are often preserved in a 20-30% salt solution called brine. how does this method prevent contamination by microorganisms

tatyana61 [14]

The salt solution (brine) is a <span> hypertonic solution. It means that there is a higher concentration of dissolved salts outside of the cell, and a lower concentration of water than the cell. If the concentration difference is too great, the microorganisms cannot survive because the cells will be dehydrated and soon die, </span>

What's the difference between meiosis and mitosis?

belka [17]

Explanation:

Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

What is hypersensitivity? Allergies? Autoimmune disorders?

JulijaS [17]

Answer:

Hypersensitivity is also known as intolerance which is defines as an unwanted reactions due to changes or interference with immune system for example allergies and autoimmunity. Hypersensitivity is the reaction of immune system that can be harmful and weakens once body.

Allergy is kind of hypersensitive reaction which is having fast response within few minutes rather than hours or days. In the case of allergies free antigens cross link with IgE on mast cells and basophils and releases vasoactive biomolecules. Few example of Allergies are anaphylaxis and asthma.

Autoimmune disorders are also a kind of hypersensitive reaction which occurs when body's immune system attacks own body cells mistakenly. few examples are Type 1 diabetes, Rheumatoid arthritis (RA), and Multiple sclerosis.

The mitochondrial DNA study indicated that there was no genetic input from Neanderthals in modern humans, but the whole-genome s

EleoNora [17]

<h2>look at the Y chromosome is the strategy </h2>

Explanation:

Finally, it is possible that front line individuals do pass on at any rate one mtDNA heredity that Neanderthals added to our genome, in any case, that we have not yet sequenced that family line in either modern individuals or in Neanderthals. Any of these explanations could underlie the nonappearance of Neanderthal mtDNA in modern human population.
Because the y chromosome inherited by paternally and mitrochondrial DNA identify the case of maternity, or parents where it helps to the person for confirmation of genome and the child parents.
look at the Y chromosome because it is paternally inherited is the correct answer.

PLEASE HELP QUICKLY! ANSWER AS MANY AS POSSIBLE. DO NOT ONLY SAY "I don't know"

WARRIOR [948]

Answer:

1. Wegener then assembled an impressive amount of evidence to show that Earth's continents were once connected in a single supercontinent. Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents.

2. It shows that all continents started from a one large land mass. It might be named Pangea. Because people are close to each other, it's so easy to talk and talk about things not just about them but also about other people.

3.Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.

4.The Lystrosaurus is a mammal-like animal from the early Triassic period that roamed modern day regions such as India, South Africa and Antarctica over 250 million years ago. It has tusks like an elephant and a beak similar to a turtle, and it was roughly the size of a pig.
