In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS
Answer:
Genotypic ratio = 16 WwDd: 0
Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit
Explanation:
This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).
According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:
WWDD - WD, WD, WD, WD
wwdd - wd, wd, wd, wd
Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.
The genotypic ratio is 4 WwDd: 0
The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

While frying French fries, Wanda burned her hand. Burns are examples of a:
skin abnormality.
homeostatic balance.
skin infection.
homeostatic imbalance.
Answer:
Damage to the skin or deeper tissues caused by sun, hot liquids, fire, electricity, or chemicals.
The degree of severity of most burns is based on the size and depth of the burn. Electrical burns, however, are more difficult to diagnose because they're capable of causing significant injury beneath the skin without showing any signs of damage on the surface.
Explanation:
hope this helps, lovely!! Have a great day <3
Answer:
D

The Cell TheoryThe smallest living things are one-celled or ____+_______________Large organisms contain millions of cells. They are many-celled or _________________ ____________________________.All of the organism's life functions are carried out by cells or parts of cells.Cells develop from other living cells – not from nonliving matter.
Answer:
unicellular; multicellular
Explanation:
The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.

A space used in industry or research settings that has a controlled level of contaminants is called a __________.
Answer:
Clean room.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.
A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

Research on laboratory rats suggests that hunger is controlled by the
A. prefrontal cortex
B. hypothalamus
C. amygdala
D. cerebellum
Please select the best answer from the choices provided
Answer:
b hypothalamus
Explanation:
The hypothalamus controls hunger and satiety. Therefore, option (B) is correct.
What is the role of hypothalamus?
The hypothalamus regulates circadian rhythms, appetite, thirst, and body temperature. The study of illnesses and diseases associated to the neuroendocrine system may benefit from using rat hypothalamic neurons.
The arcuate nucleus, or infundibular nucleus in humans, is a region of the hypothalamus that permits peripheral peptides and proteins to cross the blood-brain barrier and interact with its neurons.

25% red, 50% pink, and 25% white
Explanation:
construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.
RR is red and occurs once so that is a 25% chance (1/4)
RW is pink and it occurs twice so that is 50% (2/4)
WW is white which occurs once and it is another 25% (1/4)
can someone pls help me with this
Answer:
t= log2(2048)
The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In this case:
[tex] {t}^{2} = 2048[/tex]
[tex]t = \sqrt{2048} = 45.3h[/tex]
