Answer 1

Answer:

B.) water mold

Explanation:

The water mold is a filamentous fungus like organisms that lives in  brackish water, fresh water or wet soils. They are saprophytic, that is, they live on dead organisms. Their reproduction is usually by motile asexual spores (zoospores).The zoospores are of two types namely pear-shaped with apical flagella and kidney-shaped with two flagella on the concave side. Water mold are usually identified by their zoospores.

In convergent evolution, unrelated species or different organisms evolve similar traits, even though they live in different parts of the world.

Answers

Answer:

True  

Explanation:

Convergent evolution is a type of independent evolutionary process by which unrelated species evolve similar structural features/traits that fulfill the same or similar functions. Convergent evolution generates analogous structures, i.e., structures that have similar functions in organisms that don't share a common ancestor with such phenotypic traits. An example of convergent evolution is the wings of insects (e.g., butterflies), birds and bats. Conversely, divergent evolution is a type of evolutionary process that creates homologous structures/traits in closely related organisms because such features were inherited from a common ancestor.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. A pure bred plant with green spherical shaped seeds is crossed with a pure bred plant with yellow dented shaped seeds. State the phenotype and genotype for the parent plants p1 and p2

Answers

Answer:

The correct answer is -

P1: SSyy

p2: ssYY

Explanation:

In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.

It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.

c. When the membrane potential reaches ________an action potential spreads across the sarcolemma due to the opening of ___________
d. In response to acetylcholine binding, ________ move into the muscle fiber causing the membrane potential to rise.

Answers

Answer:

a). Voltage-gated Ca2+ channels

b). the motor end plate

c). Threshold, voltage-gated Na channels

d). sodium ions

Explanation:

a). The voltage-gated [tex]Ca^{2+}[/tex] channels are the key transducers of the membrane potential that changes into a intracellular [tex]Ca^{2+}[/tex] transients which initiates the  physiological events. When the action potential makes a contact with axon terminal, the voltage-gated [tex]Ca^{2+}[/tex] channels opens.

b). The acetylcholine is the main neurotransmitter of the parasympathetic nervous system. It helps in blood vessels dilation, muscle contraction, and perform many more functions.

It diffuses with the synaptic cleft that is located on the motor end plate of the nervous system.

c). The membrane potential is also known as the membrane voltage or the  transmembrane potential. When it recaches the threshold, the  voltage-gated Na channels opens to spread the action potential across sarcolemma.

d). The sodium ions in case of acetylcholine binding moves to the muscle fiber due to which the membrane potential rises.

A trait has two alleles, represented by p and q. If p = 0.89, what is q?

Answers

Answer: 0.11

Explanation:

According to the Hardy-Weinberg principle, it's stated that the sum of the two alleles must be 1.

In this case, we've been given that a trait has two alleles, represented by p and q and p is given as 0.89, then the value of P will be:

p + q = 1

q = 1 - p

q = 1 - 0.89

q = 0.11

Therefore, q is 0.11

Hexokinase is an enzyme that catalyzes the ATP‑dependent phosphorylation of glucose to glucose‑6‑phosphate.

a. True
b. False

Answers

Answer: The statement is TRUE

Explanation:

HEXOKINASE is an enzyme that catalyzes the phosphorylation of glucose to glucose‑6‑phosphate in glycolysis. The main function of glucose is to provide energy for the tissues. The basic pathway through which energy is gotten from glucose is through GLYCOLYSIS. The glycolytic pathway is made up of enzyme catalyzed reactions that leads to the conversion of glucose to pyruvate in the presence of oxygen or lactate in the absence of oxygen.

The first step in glycolysis is catalyzed by HEXOKINASE, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.

Therefore the above statement is TRUE.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?

Answers

Answer:

Smaller and slower axons are those related to temperature, itching and pain.

Explanation:

As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.

What is the difference between a protein and a trait

Answers

Answer:

The Relationship Between Genes, Proteins, and Traits

A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.

A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before. A protein is a molecular machine that does a specific job.

Explanation:

NOT MY WORDS! I HOPE THIS HELPS!

Genes contain the information that determines traits that are characteristics or features that are given to us or inherited from parents. Each cell in the human body contains about 25,000 to 35,000 genes.

What are Genes?

Genes are defined as the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.

Genes are defined as functional units of heredity as they are made up of DNA where as chromosome is made up of DNA which contains many genes. Each gene has a special set of instructions for a particular function or protein-coding. Genes are responsible for heredity.
