In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine?
Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: [tex]\frac{27}{100}[/tex] × [tex]\frac{100}{1}[/tex]
Firstly, divide 100% by thymine and cytosine
[tex]\frac{100}{2}[/tex] = 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%
How can change over time account for the diversity of beetles?
Answer:
Beetle diversity thus appears to have resulted from multiple factors, including low extinction rates over a long evolutionary history, codiversification with angiosperms, and adaptive radiations of specialized herbivorous beetles following convergent horizontal transfers of microbial genes encoding PCWDEs.

What is the answer to this?
Answer:
1.84 × [tex]10^{8}[/tex]
Explanation:
(2.0 × [tex]10^{8}[/tex])-(1.6 × [tex]10^{7}[/tex])
we need to make the powers the same in order to minus
(2.0 × [tex]10^{8}[/tex])-(0.16 × [tex]10^{8}[/tex]) →1.84 × [tex]10^{8}[/tex]
What prevents a lake or ocean from freezing solid?
Answer:
The surface layer of the water freezes solid creating a barrier that insulates the ice below so that it keeps a steady temperature usually a few degrees above freezing (32 degrees).

Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?
Answer:
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
Its soil contains water to extract
It isn’t too cold or too hot
There is enough sunlight to use solar panels
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!
Additional info:
Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.
Searching for life on Mars
Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.

1. How do radiation, conduction, and convection affect the atmosphere?
2. How does greenhouse effect warm the earth?
Answer:
1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.

Which of the following correctly describes how DNA contributes to the traits that appear in offspring? A) DNA contains the instructions for building RNA, which influences traits. B) DNA contains the instructions for building proteins, which create the physical traits of offspring. C) DNA contains the instructions for building carbohydrates, which are responsible for the physical traits of offspring. D) DNA contains the instructions for building enzymes, which catalyze chemical reactions for the traits of offspring.
DNA attributes to the genotype preference to the individual. DNA contains the instructions for building RNA, which influences traits. The correct statement is answer A.
What is the full form of DNA ?DNA stands for deoxyribonucleic acid.
DNA contains the orders that are needed for any organism in order to develop, survive as well as reproduce. To carry out these duties, DNA sequences are needed to be converted into messages which can be used to produce proteins in which are the complex molecules that are doing most of work in our body.
Since we have two pairs of chromosomes and we also have two pairs of genes in which one is from our father and one is from mother. These pairs of genes then determine certain physical features or traits.

Elements such as The lungs exchange gas to maintain homeostasis. In the alveoli of the lungs, oxygen and carbon dioxide are exchanged. This exchange occurs between the lungs and blood vessels (capillaries). The transport of oxygen to the blood does not require energy. The membranes of the alveoli are thin and moist and allow gasses to dissolve and be transported to and from the blood. When we breathe, a high concentration of oxygen enters the lungs and moves to the blood. Based on this scenario, is the transport of oxygen a result of osmosis, diffusion, or active transport?
Answer:
oxygen are among the few simple molecules that can cross the cell membrane by diffusion. And Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Explanation:
Answer:
This is Diffusion........... :)

Which type of bleed would typically be more urgent to treat—venous or arterial?
Answer:
Arterial bleeding is more dangerous than venous bleeding. The arteries carry blood from the body and back into the heart. If the arteries become damaged and start to bleed out, an individual can suffer loss of life within five minutes if the bleeding is severe and if no medical attention is received.

a
The genetic information is identical to the parents.
b
The offspring are made of cells.
c
The genetic information comes from the parents but is not identical.
d
The offspring inherit traits from the parents.
Answer:
c
Explanation:
Only in asexual reproduction the genetic information is identical. Sexual produces genetics that are combination of both parents, producing non-identical offspring.

I need a small text (about 50 words) for the human brain.
Answer:
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

The placenta and umbilical cord act as a life support system. What role do they play in the healthy development of the fetus?
Answer:
It attaches to the wall of the mother's uterus, and the umbilical cord extends from it, connecting to the baby. It is the baby's life support system and breathing organ while in the womb. The placenta allows oxygen and nutrients to move from the mothers blood to the fetus' blood.
