Answer:

50%

Explanation:

The punnett square cross they show you is between the genotypes Bb and bb. (See the Bb and bb at the top and right?)

Heterozygous means with one dominant gene (uppercase letter, in this case B) and one recessive gene (lowercase letter, in this case b).

The cross is already done for you. The 4 letter combinations that result from the cross of Bb and bb show as: Bb, bb, Bb, and bb. Using what we know, an individual that is <u>heterozygous</u> should have one B and one b (Bb). <u>2 out of 4</u> of the crosses are Bb. With basic math, that's then 50%.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.

Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission
Dahasolnce [82]

C) all the offspring will be genetically identical.

Explanation:

During binary fission, all the offspring will be genetically identical and little to no variation occurs.

Binary is an asexual form of reproduction which does not involve the combination of gametes from the parents.

  • During binary fission, the parent simply divides to produce young ones.
  • In this process, the offspring replicates the genetic component of the parents making it identical.
  • The offspring is a direct copy of the parents.
  • It is only in sexual reproduction that genetic materials are exchanged between the parents and offspring. This leads to genetic variation.

1. Why are new biomedical products created and what factors influence them to evolve over
Zanzabum

Answer:

Rapid progress in biomedical science has also encouraged the development of multiple successful medical technologies, but their translation into clinical use has posed complex scientific, cultural, and social problems. As demonstrated by the development of new acquired immune deficiency syndrome (AIDS) medications, the rise of these problems is spurring new interest in medical innovation.

Biomedical products are created for better results in medical technology including autoclave / sterilizer, anesthesia machine, aspiration/suction pump, and blood chemistry analyzer etcetra.

Factors influencing them includes harmful effect on other body parts ( beta blockers have harmful effect on heart), outdating technology, and introduction of evolved diseases that is not abl to cure with old products.

Describe neurulation and relate the components of a fully developed nervous system to the neural tube and neural crest.
STatiana [176]
Neurulation is termed as the folding process within which is invertebrates embryos. It includes the transformation of the neural plate into the neural tube. At this transformation of the neural plate into the neural tube. At this stage, the embryo is known as neurula. 
The process starts when notochord induces the formation of the central nervous system and this is by signaling the ectoderm germ layer which is above and it forms flat and thick neural plate.
The work of neural tube and then later differentiates to the brain and spinal chord which then forms central nervous system.
Neural tube portions forms by two different processes. for example secondary neurulation and primary neurulation.
Secondary neurulation the tube forms by hollowing out of the interior of the solid precursor
In primary neurulation, the neural plates crease inward until when the edges come into fuse and contact
