Answer:
My personal responsibility to the environment, as cataloged in the Brundtland report, is sustainability, I mean, ensuring that future generations will be able to enjoy the same quality and quantity of resources that I can have at this time, to I plan to make efficient use of services such as drinking water and electricity, make a correct separation at the source of solid waste so that the reusable material can be used and not cause unnecessary pressure on the earth's mantle, on the other hand, make a more continuous use of reusable or biodegradable material, in order not to increase pollution by waste that usually has as its final destination, in many cases, water sources such as the oceans, as well as reduce my consumption and that of my family of meat products, and products with chlorofluorocarbon gases, thus reducing the amount of gases that are deployed to the atmosphere and could destroy it.
Explanation:
The environmental commitment is something extremely important to allow there to be a true environmental sustainability beyond an advertising attractor, for this it is required that each person identify activities in which they can reduce the generation of pollutants, either through solid waste, dumping or gases. that affect the ozone layer such as methane or chlorofluorocarbon gases, these activities can regularly be carried out from our own homes and, although they may involve additional work, they will allow future generations to enjoy an environment with a quality similar to or better than the one we have currently.

Approximately 55%of an adult female body weight is water if a woman body contains 38 kg of water what is the woman's total weight
Answer: 69kg
Explanation:
Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:
55% of x = 38kg
55/100 × x = 38kg
0.55 × x = 38kg
0.55x = 38kg
Divide through by 0.55
x = 38kg/0.55
x = 69.09099
x = 69kg
Therefore, the woman's total weight is 69kg.

He designed his construct as follows: NeoR region of homology to Gene X---HSV tk--- region of homology to Gene X where Neo is the neomycin-resistance gene and HSV tk is the Herpes Simplex virus thymidine kinase gene. He transforms the ES cells and exposes them to G418 and ganciclovir. Explain to your student why he failed to recover transformed ES cells. Choose the two correct statements. a.

Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answer:
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
Explanation:
A woman's estrogen levels become highest towards the end of her ovulation. At this point, the woman is naturally prepared for a possible pregnancy. The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women. By the end of the luteal phase, the corpus luteum function declines.

A. volume increases and density decreases
Explanation:
I got a 5 on mastery test thanks to some comments on original answer
Based on the graph, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.
What is the density-temperature relationship?The density of a substance is defined as its mass per unit volume. In the case of water, the density varies with temperature, as shown in the graph. At 4°C, the density of water is about 1000 kg/[tex]m^3[/tex]. As the water is cooled, its density decreases, reaching a minimum of about 999.87 kg/[tex]m^3[/tex] at 3.98°C (this is the temperature at which water is most dense). As the water is cooled further, the density increases again, but it remains lower than it was at 4°C. The reason for this behavior can be explained by the way water molecules behave as they are cooled. At higher temperatures, the water molecules have more kinetic energy and are more spread out, resulting in a larger volume and lower density.
Hence, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis
Mitosis is the kind of cell division which allows a puppy to develop into an adult dog. So, the correct option is B.
What is Mitosis?In eukaryotic cells, a process called mitosis produces two daughter cells, each of which has the same amount of chromosomes as the parent cell. Multicellular organisms, like dogs, go through a process called mitosis during which cells divide and differentiate into different cell types.
The process of meiosis, on the other hand, produces gametes with half as many chromosomes as the parent cell and is only able to occur in specialised cells, such as the ones involved in sexual reproduction. Contrarily, homeostasis has nothing to do with cell division and instead refers to the preservation of a constant internal environment within an organism.
Therefore, the correct option is B.

Answer:
Ok so
Explanation:
1. DNA
2.A , G , C and T
3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.
5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
6. 1869
7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.
10. 20
11. A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).
12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.
