DNA and RNA are both
What are they?
Answer:
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.

Mary Anning reconstructed the fossil skeletons of many animals new to science. During her studies, she discovered that some species have become extinct.
Which of the following is one main reason a species becomes extinct?
A. overproduction
B. increased variation
C. decreased competition
D. climate change
Answer:
Hello There. The correct answer is D. Climate change.
Because it shows that Anning continued to support herself selling fossils. Her primary stock in trade consisted of invertebrate fossils such as ammonite and belemnite shells, which were common in the area and sold for a few shillings. Vertebrate fossils, such as ichthyosaur skeletons, sold for more, but were much rarer.

What are nucleic acid?Biopolymers and macromolecules called nucleic acids are necessary for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base, a phosphate group, and a 5-carbon sugar. Deoxyribonucleic acid and ribonucleic acid are the two primary classes of nucleic acids.
Nucleic acids perform a wide range of tasks, including cell development, the processing and storage of genetic information, the synthesis of proteins, and the production of energy cells.

Which paragraph in the section "Speciation" BEST supports the idea that animals can adapt in ways that allow multiple species to survive together in a common area?
Question 2 options:
A) Sometimes, an organism develops an adaptation or set of adaptations that create an entirely new species. This process is known as speciation.
B) The wide variety of marsupials in Oceania is an example of how organisms adapt to an isolated habitat. Marsupials, mammals that carry their young in pouches, arrived in Oceania before the land split with Asia. Placental mammals, animals that carry their young in the mother's womb, came to dominate every other continent, but not Oceania.
C) Koalas, for instance, adapted to feed on eucalyptus trees, which are native to Australia. The extinct Tasmanian tiger was a carnivorous marsupial and adapted to the niche filled by big cats like tigers on other continents. Marsupials in Oceania are an example of adaptive radiation, a type of speciation in which species develop to fill a variety of empty ecological niches.
D) The cichlid fish found in many of Africa's lakes exhibit another type of speciation, sympatric speciation. Sympatric speciation is the opposite of physical isolation. It happens when species share the same habitat. Adaptations have allowed hundreds of varieties of cichlids to live in Lake Malawi. Each species of cichlid has a unique, specialized diet: One type of cichlid may eat only insects, another may eat only algae, another may feed only on other fish.
Answer:
I will say C
Explanation:
Sorry if I am wrong.
Paragraph in the section "Speciation," BEST supports the idea that the Koalas, for instance, are adapted to feed on eucalyptus trees, which are native to Australia, and that this is present in the option C.
What is the significance of the koalas?They have various importance, such as being culturally significant in Australia, bringing economic benefits to the area, being important for scientific research and understanding marsupials, and so on. They are considered a vulnerable species due to habitat destruction, but they play an important role in the ecosystem as they are herbivores and help control the growth of eucalyptus trees.
As a result, paragraph in the section "Speciation," BEST supports the idea that the Koalas, for instance, are adapted to feed on eucalyptus trees, which are native to Australia, and that this is present in the option C.

Hairy stems (H) are dominant in tomato plants. Hairless stems (h) are present in tomato plants that are homozygous recessive for this trait. What genotypic ratio would we expect to see in the offspring of two heterozygous hairy stem plants? Answers are in the picture.
Answer:
The answer is A
Explanation:
A geneticist collected a population of 100 peppered moths. 36 were dark (DD or Dd) and 64 were light (dd). The alleles present in each moth were determined. Out of the 200 alleles for this gene present in this population, the gene pool contained 40 dark D alleles and 160 light d alleles. What are the allele frequencies for the two alleles in this population?
A) D = 0.36; d = 0.64
B) D = 0.50; d = 0.50
C) D = 0.25; d = 0.75
D) D = 0.20; d = 0.80
Answer:
D) D = 0.20; d = 0.80
Explanation:
Ok, so first off, we know that the number of homozygous recessive individuals is 64. So 64/100 is the q^2 value. The q value is the square root of that: it is 0.8. Because p + q has to always equal 1, the p value is then 0.2, and the p^2 value 0.04.
So, we know that the heterozygotes had to be 0.16 of the population (1-0.8-0.04 = 0.16).
d has to equal 0.8 because it is the number of recessive alleles in the population, and they give you this too. D is 0.2.
PLEASE HELP! THIS IS AN EASY EXPERIMENT BUT I DONT HAVE A PARTNER. PLEASE HELP ILL GIVE YOU 50 POINT!!!! IT won't TAKE YOU MORE THAN 10 MINUTES TO DO THIS
Instructions
1. Find a partner to complete the experiment with you. Do not do this experiment if you or your partner has a heart condition or other medical problem.
2. Take your heart rate by placing your middle or index finger on your wrist just below the thumb. Be sure to feel a distinct pulse before you proceed further.
3. Count the number of beats in 15 seconds and multiply this number by four to get the number of beats in one minute. This is your resting heart rate.
4. Record your resting heart rate in the table.
5. You should run or jump in place for 1 minute. When completed, have your partner take your pulse and record it in the table.
6. Keep track of the time and take your pulse at 1-minute intervals after you completed the initial exercise and record these results in the table.
resting heart rate:
heart rate directly after exercise:
heart rate 1 minute after exercise:
heart rate 2 minutes after exercise:
heart rate 3 minutes after exercise:
5. Have your partner complete steps two through six. Your partner should record their results below:
resting heart rate:
heart rate directly after exercise:
heart rate 1 minute after exercise:
heart rate 2 minutes after exercise:
heart rate 3 minutes after exercise:
Write a summary statement on what your results were and why? Include in your summary differences between you and your partner, your ages, your genders, your physical condition, or anything that you feel would have a bearing on your heart rate. Also, include in your summary the answer to this question: How do you think your results would change if you were 30 years older, and why?
Answer:
I did the exercise for you, and most of the summary.
Explanation:
My results were 64bpm before exercise, 96bpm directly after exercise, 76bpm 1 minute after exercise, 68bpm 2 minutes after exercise, and 64bpm 3 minutes after exercise. This is because I exercise often, which improves my cardiovascular function/fitness.
I am 19, female, and moderately fit.
Resting heart rate: 64bpm
heart rate directly after exercise: 96bpm (24x4=96)
heart rate 1 minute after exercise: 76 bpm (19x4=76)
heart rate 2 minutes after exercise: 68bpm (17x4=68)
heart rate 3 minutes after exercise: 64bpm (16x4=64)
