help asap pls getting timed

Answer:

Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)

Heterozygous B: BB (h0m0zygous)

AO x BB --> AB, BO

Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.

I hope this answer helps you find what your looking for! :)

Answer:

Primary reinforcer is innate, secondary reinforcer is a stimulus

Explanation:

While a primary reinforcer is innate, a secondary reinforcer is a stimulus that becomes reinforcing after being paired with a primary reinforcer, such as praise, treats, or money.

Answer:

A series of codons in part of a messenger RNA (mRNA) molecule. Each codon consists of three nucleotides, usually corresponding to a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C.

Explanation:

Answer: D) A and B only

Explanation:

Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.

These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.

Answer:

The answer should be A. lithosphere.

Explanation:

Firstly, let's look at the options:

C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.

B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.

Therefore, finally, we have A as the answer.

(As a sidenote, the "lithosphere" means the Earth's crust.)

Answer:

The correct approach is "Negative and Positive".

Explanation:

For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

Answer:

15.322 %

Explanation:

Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:

p² + 2pq + q² = 1, where

1- the genotypic frequency of the homo-zygous dominant allele is p²,  

2- the genotypic frequency homo-zygous recessive allele is q², and

3- the genotypic frequency heterozygous allele is 2pq  

Therefore:

q² = 0.007 >> q = √ 0.007 = 0,0836  

p = 1 - q = 1 - 0,0836 = 0.9164

2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)

Answer: Natural selection allows the survival of organisms with beneficial traits.

Explanation:

Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.

The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.

Answer:

The answer is: Growers can quickly grow disease-resistant plants from tissue cultures.

Explanation:

Took the test.

The most likely benefit of cell technology to the commercial flower industry is that the growers can quickly grow disease-resistant plants from tissue cultures. Thus, the correct option is A.

Cell technology include all the major steps such as the production, reprogramming or genetic editing of cells for the development of cell therapies or for the therapeutics which are produced by cells.

Cell technology has been found to be helpful in the development of new varieties of crops, commercial flower industry, medicinal industry for the production of cell therapies and therapeutics as well. Cell technology has been helpful for the production of disease-resistant varieties of crops.

Therefore, the correct option is A.

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.

Answer:

c

Explanation:

work=force×distance

Answer: c

Explanation:

Answer:

the gravitational field strength is 8.5 N/kg .

Explanation:

PE = mgh

where,

PE is Potential Energy

m is the mass

g (a) is the acceleration

h is the height

Substitute the value we get

→ 850 = 50×a × 2

→ 850 = 100×a

→ a = 850/100

→ a = 8.5m/s²

Acceleration is 8.5m/s².

Now, Calculating the Gravitational Field Strength

Answer:

Explanation:

The purpose of having leak and gated channels for the neuron is that the leak channels will allow the movement of sodium and potassium across the cell membrane downward from high concentration gradient to low concentration gradient. With the leakage of ions across the cell membrane, there is maintainence of a stable resting potential of cells.

Answer:

True

Explanation:

It is true because a sensor or detector is an organ that detects external stimuli from the environment or changes in both internal and external environment, it then send the information to the integrating center.

The integrating center receive stimulus or information from sensor and activate responses to the stimulus.

A aerobic is the answer

Explanation:

I took the test

Answer:

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.

Botulinum toxin

Explanation:

Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.

This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.

Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.
