In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.

The hypothalamus __________. The hypothalamus __________. influences the function of only one lobe of the pituitary gland synthe
Morgarella [4.7K]

Correct question:

The hypothalamus __________.

a) influences the function of only one lobe of the pituitary gland.

b) synthesizes all of the hormones produced by the pituitary gland.

c) regulates both reproduction and body temperature.

d) produces only inhibitory hormones.

Answer:

C) Regulates both reproduction and body temperature.

Explanation:

The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.

The hypothalamus’ main role is to keep the body in homeostasis as much as possible.

Homeostasis means a healthful, balanced bodily state.

The hypothalamus acts as the link between the endocrine and nervous systems to achieve this. It plays a part in many essential functions of the body such as: body temperature, thirst, appetite and weight control, emotions, sex drive, blood pressure and heart rate, production of digestive juices and balancing bodily fluids.

What is pancreatitis and what is the basic mechanism that underlies the condition?
svp [43]
Pancreatitis is an inflammation of the pancreas that may be caused by years of heavy consumption of alcohol of gall stones. The pancreas plays major important roles such as secreting digestive juices into the small intestines, which help to digest fats, proteins, and the carbohydrates in food. It also release hormones insulin and glucagon that regulate the blood sugar. Pancreatitis is characterized by a pancreas being inflamed, therefore when this happens the body's normal complex coordination is disrupted and the enzymes in the pancreas are prematurely activated before they exit the organ, which results in these enzymes digesting the pancreatic tissue.

Exercising causing ___________
goldfiish [28.3K]

Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
