A negative effect that conograss could have on other organizms in its habitat

1 answer:

8 0

Cogon grass is an invasive grass that is considered a pest in 73 countries and a weed of 35 crops worldwide. As a perennial grass weed, it is an inferior forage grass that negatively impacts biodiversity. It creates a very competitive environment for commercially-important species and displaces native animal and plant species. Cogon grass can also alter fire regimes.

Which body plan do you think is better, an endoskeleton or an exoskeleton? Defend your answer.

natima [27]

Answer:

I'd say an exoskeleton.

Explanation:

My main reason for saying this is because bugs with exoskeletons survive much better than bugs with endoskeletons or (surprise surprise) no skeletons. If your skeleton is outside your body, it protects everything inside you. Endoskeletons merely help hold you together.

To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A

Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e., Blood Type Genotype

A IA IA or IA i

B IB IB or IB i

AB IA IB

O ii
