composed mostly of
1. Basalt with a density of 2.7 g/cm3
2. basalt, with a density of 3.0 g/cm
3. granite, with a density of 2.7 g/cm3
4.granite, with a density of 3.0 g/cm
Answer: basalt, with a density of 3.0 g/cm^3
Explanation:
Earth's crystal bedrock on the Mid-Atlantic Ridge consists typically of basalt, with a density of 2.7 g/cm3.
What is Mid-Atlantic Ridge?A petrographic have a look at of rocks dredged from the Mid-Atlantic Ridge via way of means of the studies vessel, Atlantis, in 1947 and 1948 suggests that olivine basalt and basalt are the maximum not unusualplace rock kinds of the Mid-Atlantic Ridge.
If magma cools quickly, as an example whilst basalt lava erupts from a volcano, then many crystals shape very quickly, and the ensuing rock is fine-grained, with crystals commonly much less than 1mm in size.

A scientist wants to determine whether a certain type of yeast is able to perform anaerobic respiration. Describe a test the scientist could perform to see if the organism is capable of this.
Answer:
Follow these steps if you are unsure of the freshness of your yeast (or just want to give it a ‘good start’). See a How-to video of this test. Using a one-cup liquid measuring cup, dissolve 1 teaspoon of granulated sugar in 1/2 cup warm tap water at 110°F-115°F. Using a thermometer is the most accurate way to determine the correct liquid ...

Answer:
He could lock the plant in a room with no oxygen at all, if it survives it's anaerobic, if it doesn't then it's aerobic.
Explanation:
An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present.
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, what is
the number of daughter cells and how many chromosomes will each one have?
Answer:
for me
Explanation:
it's 25
because di is 2 and ha is 1
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
What is Diploid?Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.
According to the question, if a diploid number of an organism = 50.
This means that 2n = 50,
n = 25.
As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.
Therefore, if an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.

I need help asp due in about an hour. List three kinds of information that can be learned by sequencing DNA. Also list three specific things that have been learned from the sequence of the human genome.
Answer:
These bases provide the underlying genetic basis (the genotype) for telling a cell what to do, where to go and what kind of cell to become (the phenotype).
Whole genome sequencing is a lot like weather forecasting. It doesn't predict exactly what will happen, but gives you the chances of something happening. This means that it will tell you more about your risk for a certain disease, like diabetes, not if you have diabetes or not.
Answer:
1. any genetic information can be found through sequencing such as, eye colour, hair colour, and skin colour

Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 500 atoms of carbon-14 and 1500 atoms of nitrogen. If carbon-14 has a half-life of 5700 years, how old is the fossil? 5700 years old 11,400 years old 17,100 years old 2850 years old
Answer:
11,400 years old
Explanation:
The total number of atoms present at the beginning = number of C-14 + number of N-14 atoms.
Hence;
1500 + 500 = 2000 atoms = No
At time t, N = 500 atoms of C-14 remains
Since the half life of C-14 (t1/2) = 5700 years
N/No = (1/2)^t/t1/2
500/2000 = (1/2)^t/5700
1/4 = (1/2)^t/5700
(1/2)^2 =(1/2)^t/5700
2 = t/5700
t = 2 * 5700
t = 11,400 years old

Which of the following does not describe hormones in the body? I’ll mark the correct answer a brainliest
A. they are mediator molecules released in one part of the body but regulating the activity of cells in other parts of the body
B. most hormones enter interstitial fluid and then the bloodstream
C. hormones acts on muscles and glands only
D. hormones exert their effects by binding to receptors on or in the "target" cells
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.

which of the following best describes Mendel's idea of segregation?
A. Male offspring receive traits only from the male parent.
B. Female offspring receive only form the male parent.
C. Each parent has two copies of each gene and passes on only one copy to its offspring.
D. Each parent has one copy of each gene. each offspring receives half of its genes from each parent.
Answer:
C
Explanation:
Since we know about mitosis and sexual reproduction, each parent passes on only one copy of the gene because they got a copy of a gene from each of their parent before, and the new child will end up with two genes, one from each parent.
