Jellyfish do not have a central nervous system.

Squids which belongs to Cephalopoda (class of Mollusca) have the most complex nervous system of the invertebrates. They have well-developed senses and large brains. So, they are considered as the most intelligent of the invertebrates.

Dolphins, on the other hand, are  regarded as one the most intelligent animal.

Why are some of us more prone than others to coronary heart disease?
cricket20 [7]
"Coronary heart disease, North America’s number one cause of death, has been linked with the competitive, hard-driving, impatient, and (especially) anger-prone Type A personality. Under stress, the body of a reactive, hostile person secretes more of the hormones that accelerate the buildup of plaque on the heart’s artery walls. Type B personalities are more relaxed and easygoing. Chronic stress also contributes to persistent inflammation, which heightens the risk of clogged arteries and depression."

OR

Coronary heart disease (CHD) could be the thinning or impediment in the coronary thrombosis veins, normally brought on by coronary artery disease. Coronary artery disease (at times termed “stiffing” or maybe “blocking” in the arterial blood vessels) may be the build-up associated with trans fat and fatty deposits (named plaques) around the intrinsic artery walls.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1
