Answer:

<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.

A strain of a cereal grain can be either dark tan, medium-dark tan, medium tan, light tan, or cream colored. When a dark tan and

denis-greek [22]

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC -->1/16

RRCc, RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

The estimated daily basal metabolic rate for a man who weighs 150 lb is _____ kcal.

Nezavi [6.7K]

The estimated daily basal metabolic rate for a man who weighs 150 lb is 1636 kcal.
Basal metabolic rate is the rate of energy expenditure per unit time by endothermic animals at rest. Metabolism comprises the processes that the body needs to function. It is the amount of energy per unit time that a person needs to keep the body functioning at rest. Any increase to the metabolic weight, such as exercise, will increase the basal metabolic rate.

How were you able to determine if something was living, once living, or never living (non-living)?

snow_lady [41]

Answer:

Must have lived before.

Explanation:

For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013

There are many routes of administration that can deliver drugs directly to the developing fetus. The direct fetal routes of drug

rjkz [21]

Answer:

The correct answer is option - 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

Explanation:

Normally the drug that is provided and administrated to the fetal is through the placenta of the mother. The direct delivery of medicine can be dangerous. However, with the advancement of the medical technology direct fetal drug administration is possible and it assists in the rapid uptake of the drug by the fetus.

If the fetus requires a rapid drug effect it can be provided by direct drug delivery. Also when the placental is not working properly and affected by the disease it is recommended to provide the fetus with the drug with the help of direct delivery.

Thus, the correct answer is : 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.
