Answer:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt

Explanation:

The notation ppt refers to parts per trillion units, that is, how many parts of enzyme are there in 1 trillion parts. Percentage refers to the number of parts per 100 units. Converting the given values from percentage to ppt:

$\frac{2.5}{100}=\frac{a}{1,000,000,000,000}\\a=2.5 *10^{10}\ ppt\\\\\frac{5.0}{100}=\frac{b}{1,000,000,000,000}\\b=5.0 *10^{10}\ ppt\\\\\frac{10}{100}=\frac{c}{1,000,000,000,000}\\c=1*10^{11}\ ppt$

The concentration in ppt are:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt

Which of the following is true about mangroves?

olchik [2.2K]

Answer:

E. Mangroves have only one type of root system

Explanation:

Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.

One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.

Ovarian follicles cells produce estrogen, which is a steroid. What organelle will be present in abundance so that the follicles

zloy xaker [14]

The steroids are produced by the Smooth endoplasmic reticulum.

The cells, which are involved in the secretion of the steroid molecules have an abundant number of the smooth endoplasmic reticulum, which is abbrevated as SER.

The cells present in the ovary and the testis have a large number of smooth endoplasmic reticulum. The abundant number of smoothe endoplasmic reticulum allow them to produce a large amount of steroid molecule to produce the steroid hormones estrogen and testosterone.

Hence, in this case, the ovarian cells would have a large number of SER.

A Xw+m+Xwm female was mated to a XwmY male. Out of 1000 total F1 progeny there were 230 flies that were otherwise wild type with

deff fn [24]

In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.
$\frac{230+240}{1000}$ =0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>
