Answer:
True
Explanation:
Two strands of DNA are antiparallel to each other because they appear in opposite direction and are mirror image and they are read in 5' - 3' direction which also refers to the orientation of nucleotides of a single strand of DNA and the reading would start from the free phosphate and it will end at the hydroxyl group

Organisms pass traits from one generation to the next. Traits are-
Answer:
inheritance
Explanation:
The transmission of traits from one generation to the next is called inheritance, or heredity (from the Latin heres, heir). However, sons and daughters are not identical copies of either parent or their siblings. What does "variation" mean in terms of sexual reproduction?

How is a whale more like a human than a fish? CHOOSE ALL THAT APPLY 1.warm blooded 2.breast feeds its young 3.spends much time out of the water 4.can hold its breath for long periods of time
Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
Which statement BEST represents a hypothesis
A: the birds ate 10 mg of food
B: the mice have gray colored fur
C: if rabbits eat twice there normal Amount of food, they will gain weight
D: the fish in the aquarium died becuase the water temperature was too high
Answer:
I think C. would be the correct answer but I'm not 100% sure if that's correct.
(If you think I'm wrong then DONT say C is the answer.)

1) Define biodiversity in your own words:
2) Why is biodiversity important?
Answer:
Explanation:
1.) Biodiversity is variety in an ecosystem and the living things inside of it. It means all the different species and creatures that live on the planet.
2.) Biodiversity is important because it provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, erosion control, and crop and tree pollination. Each species ina n ecosystem has a role to play.

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.

Three students are arguing about the reason that an apple appears red. Student A claims that it is because an apple absorbs the color red and reflects all other colors away from it. Student B claims that it is because an apple absorbs every other color of light and only reflects red light away from Student C argues that the apple gives off its own rays of red light. With which student do you agree and why?
Answer:
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. ... For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum.

adaptation of nerve cell
Answer:
They have a long fiber so they can carry messages up and down the body over long distances. In a stimulated neuron, an electrical nerve impulse passes along the axon. The axon is insulated by a fatty sheath - the fatty sheath increases the speed of the nerve impulses along the neuron.

According to the diagram how are the three components
of a nucleotide important to the structure of DNA?
Answer:
A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.
Abiotic Factors and biotic factors in the oxygen cycle
Oxygen cycle The cycling of oxygen between the biotic and abiotic components of the environment (see biogeochemical cycle). ... In the process of respiration oxygen is taken in by living organisms and released into the atmosphere, combined with carbon, in the form of carbon dioxide.

You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when you cross them you make F1 plants that are Cyan in color (a light aqua color). The ratio of offspring is as follows: There were 42 plants with Blue flowers (R1), 39 plants with Green flowers (R2) and 86 plants with Cyan flowers. Is the number of your progeny consistent with a single-gene incomplete dominance inheritance pattern
Answer:
Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.
Given:
R1R1 = 42
R2R2 = 39
R1R2 = 86
Total R1 alleles = 2*42+86 = 170
Total R2 alleles = 2*39+86 = 164
Total alleles = 334
Frequency of allele R1 = 170/334 = 0.51
Frequency of allele R2 = 164 / 334 = 0.49
Expected number of each phenotype:
Total population = 167
Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44
Green = R2R2 = 0.49 * 0.49 * 167 = 40.10
Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46
Phenotype Observed(O) Expected (E) O-E (O-E)2 (O-E)2/E
Blue 42 43.44 -1.44 2.0736 0.0477
cyan 86 83.46 2.54 6.4516 0.0773
green 39 40.1 -1.1 1.2100 0.0302
Total 167 167 0.1552
Chi-square value = 0.155
Degrees of freedom = no. of phenotypes – 1
Df = 3-1 = 2
Critical value = 5.99
Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.
disturbance destroying an area through the climax of ecological succession
Answer:
hope this helps
secondary succession
Explanation:
Large, low intensity disturbances, such as plowing in conventional agriculture, result in moderate amounts of succession, where species can survive in the soil and quickly recolonize areas after a disturbance. This type of succession is often called secondary succession
What is Climate Change?
Explain your answer.
What is Climate Change?
Climate change is a change in the usual weather found in a place.
How it helps us:
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
How it works:
As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.
How it affects us:
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

stay safe healthy and happy.During mammalian embryogenesis, the first differentiation event that occurs leads to a polarization of the outer cells of the 16-cell morula. This outer layer of cells forms the trophectoderm and the inner, apolar clump of cells become the inner cell mass. The inner cell mass will give rise to:
Answer:
the entire embryo
Explanation:
The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.
