Q1 when does an embryo implant in the wall of the uterus
q2 suggest y pregnant women cant take some medications

Answers

Answer 1

The fertilisation occurs in the fallopian tube. By about the fifth day after fertilisation, the embryo finally reaches the uterus, where it implants itself in the endometrium, or uterine lining. Furthermore, implantation of a fertilised ovum is most likely to occur around 9 days after ovulation, however, this can range between 6 and 12 days.

Answer 2

Not all but certain medicines should not be taken by pregnant women because it can increase blood pressure, thinning of blood and it can increase contraction in the uterus causing the uterine lining to shed leading to miscarriage.

What is a "foram"? Where can it be found today?

Answers

What are they?

Foraminifera (Foram) are members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell of diverse forms and materials. Tests of chitin are believed to be the most primitive type.

Where can they be found?

Foraminifera are found in all marine environments, from the intertidal to the deepest ocean trenches, and from the tropics to the poles, but species of foraminifera can be very particular about the environmentin which they live.

In pea plants, purple flowers are dominant over white flowers. The phenotype ratio of purple to white flowers in a population of five plants is 4:1. How many plants have white flowers?1
2
4
5
----------


In some lizard species, a short tail is recessive and a long tail is dominant. According to the principle of dominance:
a lizard with a TT genotype will have a short tail
a lizard with a tt genotype will have a long tail
a lizard with a Tt genotype will have a short tail
a lizard with a tt genotype will have a short tail

Answers

1. 1
Since the ratio is purple flowers to white flowers, and the ratio is 4:1 out of 5 plants, there is 1 white flower. Remember that, in a ratio, the first number is the first one mentioned, and the second number is the second one mentioned.

2. A lizard with a tt genotype with have a short tail
Since the short tail is recessive, it can be represented with a lowercase letter (t), and since the long tail is dominant, it can be represented with a capital letter (T). Because the long tail gene is dominant, if even one capital T is present in a genotype, the lizard will have a long tail. You can label the different kinds of genotypes if it helps.

TT - long tail, since both genes are for a long tail
Tt - long tail, since one gene is for a long tail, and the long tail is dominant
tt - short tail, since both genes are for a short tail

Hope this helps!

What is a complementary nitrogenous base​

Answers

Answer:

Each nucleotide base can hydrogen-bond with a specific partner base in a process known as complementary base pairing: Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. These hydrogen-bonded nitrogenous bases are often referred to as base pairs.

Manuel is performing a scientific investigation to determine whether fertilizer A or fertilizer B is more effective at increasing the growth rate of tomato plants. Manuel measures and separates 30 tomato plants into two equal groups that are planted in identical environments. He gives one group fertilizer A, and gives the other group the same amount of fertilizer B. During the first week of the investigation, he gives the tomato plants in both groups the same amount of water. During the second week, however, he forgets to water the tomato plants being given fertilizer B, but still provides water for the tomato plants being given fertilizer A. Two weeks after planting, Manuel measures the tomato plants and discovers that the tomato plants given fertilizer A have grown much more rapidly than the tomato plants being given fertilizer B. Manuel's resultsA. are not valid because one of the variables was not controlled during week 2. B. are valid because he controlled all of the variables in week 1. C. are valid because he designed his experiment correctly. D. are not valid because he should not have grown the plants in identical environments.
