The change in the wind patterns on the Earth that causes an increase in ocean temperature is:
a.
El Niña
c.
La Niña
b.
El Niño
d.
La Niño
eep ofc i don’t know! also why isn’t science a subject i can choose?
Answer:
B
Explanation:
El Niño conditions happen when surface water in the equatorial Pacific becomes warmer than average and east winds blow bleaker than normal.
these occur usually every 3-5 years. it is also referred to as ENSO (El Niño-Southern Oscillation)
the opposite condition is call La Niña.
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.
Which factors increase the heat absorbed by a land surface? Select the two correct answers. (1
becoming paler
becoming smoother

The heat absorbed by the land and oceans is swapped with the atmosphere by the means of conduction, radiation, and latent heat. By removing plants, and removing snow increase the heat absorbed by a land surface, i.e., option C and D.
What are the means of heat transfer?Heat transfer is a mechanism of conveying energy and entropy from one location to another.
It can be done by either of the following:
Conduction.Convection.Radiation.Factors increase the heat absorbed by a land surface are by removing snow and by removing plants.

How do mutations happen?
Answer:
HOPE THIS HELPS
Explanation:
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke

Your student is trying to create a "Gene X" knockout mouse by introducing a recombinant construct into embryonic stem (ES) cells, selecting transformants, and introducing the transformed cells into mouse blastocysts. 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. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be sensitive to ganciclovir and neomycin, and would die.
b. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to ganciclovir, but sensitive to neomycin, and would die.
c. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to ganciclovir, but resistant to neomycin, and would die.
d. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin and ganciclovir, and would die.
e. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin, but resistant to ganciclovir, and would die.
f. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to neomycin, but sensitive to ganciclovir, and would die.

In the beginning man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing.
a. True
b. False
Answer: True
Explanation:
The statement that "In the beginning, man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing" is true.
The creatures that were different from man became self supporting soon. If the present form had been the original form of man, he won't have survived.

Guys helpppppp please and I hope y’all have a great day
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.

the number and percentage of eukaryotic species that are still to be formally described is to be beauty
Eukaryotic organisms are species that have defined nucleus and membrane limited organelles. Total 11% or 250,000 are described while 97% or 8490000 are yet to be described.
What is the population of the eukaryotes?Eukaryotes are the largest and the most dominating species that includes kingdom plants, animals, fungi and protists. A total of 8.74 million eukaryote species on Earth are present from which only 250,000 are described.
Eukaryotes are the species that are well-defined organisms that contain the genetic material enclosed within the nuclear membrane and the organelles are also enclosed.
With new discoveries and findings, many new species are described that are grouped into one of the kingdoms based on their properties and features.
Therefore, 8.74 million eukaryote species are present on Earth.

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.
