Write a summary statement for saturated fats including whether they are solids or liquids at room temperature and weather they have all single carbon-to-carbon or at least one carbon-to-carbon bond

Answers

Answer 1

Answer:

Answer:

A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated because the second bond is broken and each half of the bond is attached to a hydrogen atom.

Explanation:

Answer 2

Answer:

Answer:

saturated fats consists of single covalent bond and they are solid at room temperature and their melting point increases with increasing chain length

If the green nitrogen base in the DNA model represents adenine, the blue nitrogen base COULD representA) adenine
B) guanine
Eliminate
C) thymine
D) uracil

Answers

Answer: The correct answer is-

B) guanine.

DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms. It is made up of small units called nucleotides. A nucleotide is hat is composed of -

1)nitrogenous base, which can be Adenine, Thymine, Guanine, Cytosine

2) Phosphate group, 3) Deoxyribose sugar.

In a DNA molecule, Adenine pairs with Thymine, and Guanine pairs with Cytosine as per the Watson and Crick base pairing.

If the green nitrogen base in the DNA model represents adenine, this indicates that thymine will also be green ( as it pairs with adenine).

Thus, the blue nitrogenous base will be represented by Guanine.

Answer:

B) guanine

A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. Which most likely describes why he did not identify the insect?

Answers

The answer to this question is letter C. The organism evolved during identification.
A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. He was not able to identify the insect because the organism evolved during identification.

Choices to this question are:
A) The scientist must have made a mistake.
B) The insect might be an unknown variation or a new species.
C) The organism evolved during identification.
D) The dichotomous key had to many questions.

Answer;

The insect might be an unknown variation or a new species.

Explanation;

A dichotomous key is a biological tool that is used by scientists to identify unknown organisms. It is used to identify organisms in an ecosystem such as trees, mammals, fish, etc.
Dichotomous key consist of a series of steps or statements about a specific characteristics of organisms that leads to the correct name of a given organism.
If the scientist went through all the possible steps correctly in a dichotomous key and was unable to identify the insect, it means the insect might have been unknown variation or a new species.

Sodium has the atomic number 11. How many electrons are in a sodium ion, which has the symbol Na+?

Answers

Since Na has the atomic number 11, it has 11 electrons

Thus the ion Na+ has 11-1=10 electrons.

Sodium has the atomic number 11. How many electrons are in a sodium ion, which has the symbol Na+? the awnser would be 10, 10 electrons.

The most easily polluted groundwater reservoirs are A. water-table aquifers.
B. sewage plant reservoirs.
C. salt reservoirs.
D. artesian wells.

Answers

The most easily polluted groundwater reservoirs are water table aquifers.

Further Explanation:

A water table explains the boundary that lies between water saturation and unsaturation ground. It is present below the rocks and soil. The water that lies after the water table is aquifers. Soil, rocks, and sediments purify it. The water table is raised through rain, snow and irrigation process. Its concentration depends on the season; it is at its higher level during the rainy season.

Sometimes, the water table crosses with a land area such as spring water and an oasis. It is exposed to the land surface from the region like canyon and cliff. The area below the pumice carries porous and light rocks that can hold more water than denser rocks. This area carries a fuller aquifer. The United States completely depends on the groundwater due to which it is more susceptible to get polluted. It occurs when the human-made substance such as oil and chemicals enters the underground water. The groundwater absorbs the fertilizer and pesticides used on crops. Therefore, it is easier to contaminate the water table aquifers.

Which statement describes natural selection

Answers

Where is the statement?

Answer: You didn't put any statements lol

Explanation:

But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)

A closer cross-section view of a stem revealed continuous rings along the interior of the stem. Which type of stem could it be?

Answers

A stem with continuous rings along the interior is likely to be a woody dicot stem. Each xylem, the number of which increases by one a year, creates a ring. This is, for example, how trees are dated, by counting the number of rings in their trunks.

The answer is B.) Woody dicot
