Answer:
The Senses are:How does natural selection contribute to the theory of evolution?
Answer: Natural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve.

Algae are the primary producer in the trophic levels. Therefore, option "C" is correct.
What are tropic levels?Tropic levels are the levels or steps in the food chain. In tropic levels, the energy is transferred to different levels through food produced by the lower levels. The source of nutrition varies in different food chains.
There are four types of tropic levels, first primary producers are the autotrophs which produce their own food. Second, are herbivores which consume the autotrophs also called primary consumers. Third are secondary consumers who are carnivores and fourth are the tertiary consumers who are also carnivores.
example: sun, plants, deer, and tigers.
Tropic levels play a key role in understanding the flow of energy.

Which two natural resources will be most affected as people try to meet the growing demand for food?
Answer:
water and land
Explanation:
I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.

Samples 1 and 4
Samples 3 and 4
Only sample 4
Aquatic toxicity is found in the four sample sites. But since the water uptake facility collects water from upriver, the correct option is C. Samples 3 and 4.
What is aquatic toxicity?Aquatic toxicity is the property of a substance to causes harmful effects on aquatic or water-dependent organisms.
Aquatic toxicity can be either,
Sharp ⇒ nocive effects after a short exposition periodCronic ⇒ nocive effects after a long exposition periodAquatic toxicity depends on the substance type and its concentration in water.

According to the problem statement, toxic levels are reached when
nitrates are greater or equal to 10 mg/Land/or
carbamates are greater or equal to 0.04 mg/L.Sample 1 ⇒ Two miles downriver from drinking water uptake facility
Nitrate → 12 mg/L ⇒ > 10 mg/L ⇒ toxic Carbamate → 0.06 mg/L ⇒ > 0.04 mg/L ⇒ toxicSample 2 ⇒ One mile downriver from drinking water uptake facility
Nitrate → 9 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 2 mg/L ⇒ > 0.04 mg/L ⇒ toxicSample 3 ⇒ One mile upriver from drinking water uptake facility
Nitrate → 8 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 0.04 mg/L ⇒ = 0.04 mg/L ⇒ toxicSample 4 ⇒ Two miles upriver from drinking water uptake facility
Nitrate → 10 mg/L ⇒ = 10 mg/L ⇒ toxicCarbamate → 0.05 mg/L ⇒ > 0.04 mg/L ⇒ toxicThe four sample sites have toxic levels. Both of the substances concentrations or at least one of them reaches the toxic level at each site.
However, since water uptake facility can colect water from upriver, we only need to consider these sample sites.

A. words and language in context.
B. behavior skills.
C. listening skills.
D. language and speaking skills.
Answer: B
Explanation: behaviour is learnt from action not speaking
The right response is C: listening abilities. Adults may teach toddlers a variety of crucial lessons that support language and speech development by speaking naturally to them. Setting a good example for children on how to use language in context is one of the most crucial things adults can do.
What is the deal with the samples ?This entails showing them samples of the language to use in various contexts and encouraging them to use the appropriate nouns and verbs. Children benefit from this because it enables them to appropriately grasp and apply the words they hear.
By giving children examples of appropriate behaviour in various contexts, adults may also assist youngsters in developing their social skills. This can involve things like greetings, apologies, or handling situations.disagreements.
Adults may teach kids how to respectfully communicate their thoughts and feelings. Finally, by engaging in conversation with kids and giving them feedback, adults may aid in their language and speaking development.
This might involve things like teaching kids to express themselves clearly and concisely, correcting grammatical errors, and explaining terms and phrases. However, normal conversation is not an effective way to teach listening skills.

Answer:
DNA: thymine, deoxyribose, large molecule, stay in the nucleus
RNA: single strand, uracil, leave the nucleus, small molecule
Explanation:
As for single strand, it's well known that DNA has two strands while RNA has one.
For the description that asks about thymine, you have to remember the nucleotide bases in DNA and RNA. Remember that DNA's bases are A, C, T, and G, while RNA has all the same bases except for T (which stands for thymine). In RNA, the thymine is replaced with uracil, usually abbreviated as U. That sorts out the descriptions that ask for thymine and uracil.
To figure out the one that asks for deoxyribose, remember that DNA has deoxyribose and RNA has ribose (hence why DNA is deoxyribonucleic acid while RNA is just ribonucleic acid.)
For the large molecule/small molecule ones and the questions that ask about the size of the molecule, remember that DNA is a way bigger molecule than RNA and that RNA is small enough to leave the nucleus, while DNA is much too valuable to the cell to be able to leave the nucleus.
