Answer:
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.
deficiency symptoms of molybdenum in photosynthesis
Answer:
Molybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: pale leaves with interveinal and marginal chlorosis (yellowing) and necrosis (scald);

In a non-mutated DNA strand, what base pairs with guanine?
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Explanation:
Answer:
cytosine pairs with guanine.

How do the process of DNA replication and the laws of inheritance help cells and individuals pass on their
traits?
DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution. Also, DNA copying helps in transfer of information or characters from the parents to the offsprings.
Mendel studied traits with only one mode of inheritance in pea plants. The inheritance of the traits he studied all followed the relatively simple pattern of dominant and recessive alleles for a single characteristic. There are several important modes of inheritance, discovered after Mendel’s work, that do not follow the dominant and recessive, single-gene model.

Are sea sponges closer in relationship to humans, boxwood shrubs, paramecium, or moss? Explain using evidence to support your claim.
Answer:
Humans
Explanation:
A new research now suggests that possibly the entire animal kingdom, including humans, shares important genetic mechanisms with sea sponges. Now published in the journal Science, the discovery has been made by a team of scientists led by Dr. Emily Wong from the Victor Chang Cardiac Research Institute and UNSW Sydney.

Which of the following is an example of artificial selection?
Answer: last option
Explanation:
artificial selection is when humans basically pick a desirable trait in a species and take steps to enhance or perpetuate that specific trait so that it's more common
the best option to describe this is the last one, because humans have bred domestic dogs to be less aggressive and more playful or friendly
In unicellular organisms a single cell carries out all life processes then why do multicellular organisms need tissues?
Answer:
Its very easy here see we human being and animals are mutlicelluar organism We have different cells which form tissues and tissues forms organs and organs form human body
Each and every cells and tissues have their own work and functions to do
Which means that if we have absence of heart in our body we can't live because heart tissues help us ro Survive
Directions: Consider a pedigree that is tracking an autosomal recessive trait, where two recessive alleles (tt) result
in the inability to taste a chemical known as PTC. The ability to taste PTC is determined by the presence of a
dominant allele (T). Complete the missing boxes in the chart. The first row has been done for you as an example!
Note: The ability to taste PTC may be more complex than a simple gene trait.

which organism has the least energy grass--> rabbit--->raccoon---> wolf
Answer:
The Wolf
Explanation:
Food chain follows a law called 10% Law.
It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.
Hence wolf has the least energy
Herbicides are chemicals that kill plants by interrupting important biological processes. Different herbicides affect different plant processes. The herbicide atrazine prevents the chemical reactions that use energy from sunlight.
A plant is sprayed with atrazine.
Exposure to atrazine causes an immediate decrease in the production of two substances in plant. Select the substance.
A. DNA
B. Carbon dioxide
C. Oxygen
D. Phospholipids
Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
A herbicide is a type of pesticide that is used for controlling the weeds so that the plants can get nourishment. They are common weed killers used to clear taw waste groups and constructional areas.
These herbicides are used for different plants and prevents the chemical reaction that makes use of energy. The plants are sprayed with the chemical called atrazine which is used to decrease the production of oxygen.Hence the option C is correct.

Why does tissue fluid does not contain RBC?
Explanation:
The plasma that filters through the blood capillaries into the interstitial fluid does not contain red blood cells or platelets as they are too large to pass through but can contain some white blood cells to help the immune system.

Decomposers are important in the environment because they
A. convert large molecules into simpler molecules that can then be recycled
B. release heat from large molecules so that the heat can be recycled through the ecosystem
C. can take in carbon dioxide and convert it into oxygen
D. convert molecules of dead organisms into permanent biotic parts of an ecosystem
Answer:
D
Explanation:
Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).
What are Decomposers?Living organisms such as micro-organisms that convert dead plants and animals into humus are known as decomposers. Fungi and bacteria fall in this category. It recycles and converts the dead matter into humus which mixes with the soil of the forest. It provides essential nutrients to the plants. It is also known as detritivores.
There are four types of decomposers, namely
FungiInsectsEarthwormBacteriaThese types of organisms decompose or break down organic matter such as the remains of dead organisms, carrying out the process of decomposition, which occurs after the death of all living organisms.
They are also called reducers because they are able to remove or degrade dead bodies of organisms and because of their small size they are known as micro consumers.
Thus, Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

Neutral theory proposes that
A) molecular clocks are more reliable when the surrounding pH is close to 7.0.
B) most mutations of highly conserved DNA sequences should have no functional effect.
C) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral pH.
D) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral electrical charge.
E) a significant proportion of mutations are not acted upon by natural selection.
Answer:
The correct answer is E) a significant proportion of mutations are not acted upon by natural selection.
Explanation:
The neutral theory, proposed by Motoo Kimura in 1968, proposes that part of the molecular variability produced by mutations that exists in populations is natural variability, that is, a large part of the genetic variation observed in populations is due to random fluctuation of genetic variants that are neutral, on which natural selection hardly acts, so they are not an evolutionary force since they do not contribute predominantly to natural selection and proposes genetic drift as an evolutionary mechanism.
