Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.
Explanation:
The atomic no. of carbon=6
Electronic configuration=2,4
The atomic no of H=1
E.C=1
The atomic no of O=8
E.C= 2,6
Therefore to attain octate state, they will share electrons

→Do EM waves travel faster in denser matter←
good answers only, BAD ANSWERS GET REPORTED
Answer:
No
Explanation:
Electromagnetic waves travel slowest in dense matter such as solids. On the other hand, mechanical waves travel quickly through solids. For example, sound travels fastest through solids. This difference is because EM waves do not rely on the movement of particles to travel. Since they require no medium they can travel the fastest in space or other vacuums.

Which shape has four equal side lengths? (2 points) a a quadrilateral with one small square in each of the four corners, and single arrows going in the same direction for one pair of the opposite sides and double arrows for the other pair of opposite sides b a quadrilateral with double arrows going in the same direction for one pair of the opposite sides c a quadrilateral with sides of different lengths d a quadrilateral with a short line on each side
Answer:
D. a quadrilateral with a short line on each side
Explanation:
This question is describing a SQUARE, which is a quadrilateral with four sides equal. A square has four angles as well, which are of equal sizes as well i.e. 90% each.
A quadrilateral with one small square in each of the four corners showing that each angle is a right angle (90°). In a square, same line are on each side showing that any side with the short line has the same length, hence, all sides have an equal length.

Would the human body want to get back to its optimal (best) settings for temperature, glucose levels, etc.? Explain your answer .
Explanation:
Introduction. The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

Question 2: Case 2
A young woman who was adopted at birth, comes into your office asking you to help her identify her birth father. She
already knows that the blood type of her birth mother is A positive. She knows her birth father is one of three men who are
willing to help in her search. Your first step is to do a blood test on the daughter. Your results show that she is type AB
negative. You make some phone calls and have the three possible fathers come in to give a blood sample. Here are the
results:
• Man #1 - O negative
• Man #2 - B negative
• Man #3 - AB positive
From this information, can you conclude who the father is? Is there anyone you can exclude? What tests could you do further
to confirm your analysis about who the father is?
Answer:
man3

During MEiosis, the chromosomes are COPIED: *
10 points
Once
Twice
The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. ... In humans, the reduction division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one discarded polar body.

What are the reactants in
photosynthesis?
Explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

3. Apply Concepts Write a brief expla-
nation for the results in the table
using information about phenotypes
and genotypes in blood group
genes.
Answer: Since blood type A carries the A antigen, it can only recieve blood with type A or type O in it, so it can only make blood transfusions with a type A, or type O blood donor. Same goes with blood type B, it can only receive blood from B or O blood donors. As for type AB recipients, they can receive blood from any blood types, (A B AB and O). For type O recipients, they can only receive blood from another type O donor. This is why some parts of the table have unsuccessful transfusions because the blood cells will not recognize the other blood type cells coming into your body, so they will see them as invaders.

Which of the following are not properties of lipids?
Answer: Lipid refers to any class of organic compounds that are considered fatty acids. This also includes their derivatives that are soluble in organic solvents, like many natural oils, waxes phospholipids and steroids.
All lipids have similar properties because their molecules are made of the same elements with similar chemical structure that only varies slightly.
Foods like meat, poultry, seafood, beans, peas and eggs are all sources of proteins, while good that contains saturated fat like palm oil, coconut oil, milk, cheese and coffee creamers and butter contain lipids, that may help in storing energy.

bAnswer:
Explanation:
Variation in genotype is caused by
O None of the above
e phenotypes changing more quickly than genotypes.
o recombination of genes as a result of sexual reproduction.
O
O mutations only.
Answer:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
Which process is absent in animal cells?
A.(making proteins)
B.(chemical reactions)
C.(respiration)
D.(photosynthesis)
The process that is absent from animal cells is photosynthesis. The correct option is D.
What are animal cells?Animal cells are present in animals, and they are of two types, prokaryotic and eukaryotic cells. These cells are different from plant cells as they do not contain a cell wall.
Plants are autotrophic organisms that do the process of photosynthesis to perform the chemical reaction to make food. As animal cells are heterotrophic, they do not perform photosynthesis, and they do not contain chloroplast, but chloroplast is present in plant cells.
All other processes like making protein, chemical reactions, and respiration. These processes are performed by both animals and plant cells. These are necessary for both plants and animals.
Thus, the correct option is D. photosynthesis.

How and why do plants need to be able to respond to their environment?
Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can't run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant's primary means of response is to change how it is growing. hope it helps have a great day and I hope you pass:)
