Answer:

Dry eyes

Explanation:

The lacrimal glands are two glands, one for each eye, that produce the aqueous layer of the tear film. The lacrimal glands produce tears which then flow into canals that connect to the lacrimal sac. From this sac, the tears drain through the lacrimal duct into the nose. A symptom of an under-producing lacrimal gland would be dry eyes.

A symptom would be dry eyes, since this is the gland in your eye that produces tear film.

sergiy2304 [10]

Answer:

This question is incomplete, the complete part is asking to identify the variables of the experimental statement i.e. dependent and the independent variables.

Independent variable: different amounts of time light is on

Dependent variable: Number of eggs laid by chicken

Explanation:

In a scientific experiment, variables, which are factors that can be altered, are used. These variables are independent and dependent variables.

An independent variable is that variable that is subject to manipulation or control by the experimenter in order to bring about a change in the dependent variable. For this experiment, the independent variable is the DIFFERENT AMOUNT OF TIME LIGHT IS ON.

On the other hand, a variable is said to be dependent if it is the measurable or responding variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the NUMBER OF EGGS LAID BY CHICKENS. The number of eggs laid (dependent variable) is dependent on the amount of time light is on (independent variable).

Patterns of inheritance are usually more complicated than what is predicted by Mendelian genetics. Explain four possible excepti
Vinvika [58]

Answer:

Please find the explanation of the four possible exceptions to Mendelian genetics below.

Explanation:

Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:

- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).

- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.

- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.

- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.
