Answer:
Spleen
Explanation:
The is because the spleen is an organ found in upper section of the abdomen spleen acts as a filterand it help to remove old and damaged cells . It also play a major role in controlling the amount of blood and blood cells that move round the body. The spleen also helps remove pathogens. It contains white blood cells called lymphocytes and macrophages.
The connective tissues of mammalian brain is called the meninges. There are three layers of this tissue. The outer layer is called the dura mater. The arachnoid is the middle layer and the pia mater is the inner layer of it.
Answer: The combination produced is RRtt.
The combination rrTt does not appear in this punnett square.
Explanation:
As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.
<u>A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment.</u> It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.
Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.
The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.
To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.
Answer:
Water
Explanation:
When a colloid such as a gelatin forms, water is entrapped by the process of protein coagulation.
Colloids can be describes as particles of solid having spherical diameter between 1 and 100 nm which are dispersed in the liquid medium. Coagulation can be described as a process in which particles aggregate and lead to the formation of flocs. Flocs can either settle in water or can easily be seperated from water.
