Answers

Answer 1
Answer:
mast cells, melanocytes, nerve cells, cardiac muscle cells
Explanation:
There are lots of examples of specialized cells, but here are four.
Mast cells - release histamine and heparin, which are important in directing the inflammatory response. These cells direct the first line of defense in preventing infection
Melanocytes - release melanin, which is a brown pigment that gives skin and hair its color. This is an important process because melanin reflects UV light, which can damage DNA in skin cells
Nerve cells - specially designed to allow nerve impulses (called action potentials) to travel throughout the body. They use electrical signals to allow the whole body to communicate
Cardiac muscle cells - responsible for muscle contraction of the heart. They have specialized structures like intercalated discs that allow rapid communication between cells. This is important because every cell in the heart has to contract at the same time to allow blood to flow properly throughout the body.
The specialization of cells in organisms is important because it allows us to do many specialized functions. Non-specialized cells are pretty limited in what they are able to do, so they are small and inefficient. Specialized cells also help prevent disease, which is the opposite of homeostasis.

Answer:

Broccoli is a dicot

Explanation:

I looked it up on the internet :)

Unlike monocots, the pollen grains of dicot plants have three pores and are called trisulcate. Dicot plants can also have bark and secondary growth increases the diameter (girth) of the plant.

A disputed paternity case! Hermione’s new baby has a blood type of O. Her blood type is B and Ron Weasley is A. Harry Potter (blood type AB) insists he is the child’s father. CAN THIS BE TRUE???!

Answers

Answer:

No becuase one of the parents needs to have type O

Explanation:

No, this cant be true because in order for a child to have O blood type  parents must have a recessive allele "[tex]i[/tex]".

What type of alleles are blood types?

An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele.

Codominant alleles in humans are responsible for determining blood types. There are three distinct alleles, and they are denoted by the letters IA, IB, and i. The IA and IB alleles both have co-dominant inheritance, but the i allele has a recessive inheritance pattern. Type A, type B, type AB, and type O are the four different human phenotypes that are possible for the blood group.

Therefore, in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]"

Which is the better soil amendment: compost, vermiculite, and manure? Why?

Answers

Answer:

All of them are great, but compost and manure are probably best because they still have protiens and energy stored in them.

Have an awesome day friend! :D

Explanation:

Compost: (permeability, water retention, nutrients) Well-rotted compost is one of the best soil amendments you can add to your garden, and it’s impossible to use too much! Compost is highly fertile and lightens heavy soils while providing structure to loose soils. It also possesses the amazing ability to help soil retain much needed water while improving drainage – making compost great for both clay and sandy soils. Compost lasts about six months but has a long-term impact on soil microbes and overall fertility. Continue to add compost, and watch your soil get better and better.

Greensand: (provides permeability, nutrients) This powdered rock material provides slow release nutrients, such as potassium and other trace minerals. It also helps loosen compacted soil.

Sand soil amendment

Sand soil amendment.

Gypsum: (permeability for saline soils) While powdered gypsum is considered an amendment for clay soil, it’s actually more important for saline soils where it loosens the clay by reacting chemically with the salts.

Leaf Mold: (water retention, texture, nutrients) Made from shredded, composted leaves, leaf mold holds moisture, loosens soil, provides organic matter, and breaks down slowly to improve overall soil texture. Leaf mold also encourages beneficial microbes that help transfer nutrients to plant roots.

Manures: (texture, nutrients) Composted manures are affordable, readily available soil amendments. Like other forms of compost, manure provides the right balance of drainage and water retention. Manures are high in nitrogen and other nutrients, so they’re particularly useful as slow release fertilizers. Manures can add salt to the soil, so they may not be suitable if your soil is already saline. Use only well rotted manure to prevent burning due to high nitrogen content.

If you place yeast, sugar and water in a sealed bag and in the sun , what two things will be produced

Answers

Answer:

Explanation:

The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.

While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment​

Answers

Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.

During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.

The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.
