Briefly explain how an animal's role in the agricultural industry determines its most desirable traits as livestock
Answer:
The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

The organisms that would most likely to be seen return to the ecosystem first is small grasses and insects. Thus, option A is correct.
What is an ecological pyramid?An ecological pyramid of number refers to a graphical representation which is created to show the number of organisms at each tropic level in a particular ecosystem. The pyramid has the largest size at the bottom and get smaller as the pyramid goes up.
The primary producers, which are plants are the ones that are usually found at the bottom of the pyramid and they are normally more than the consumers. Consumers are divided into primary, secondary and the tertiary consumers. The tertiary consumers are usually located at the top of the pyramid and they are often the smallest in number.
Therefore, The organisms that would most likely to be seen return to the ecosystem first is small grasses and insects. Thus, option A is correct.

Explain how hormones recognize their target cells
Answer:
A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
Why is glucose needed for cellular respiration to produce ATP?

imagine that ou are stduying a very large population of moths that is isolate d from gene flow.A single gene controls wing color.Half of the moths have white spotted wings (genotype WW or Ww) and half of the moths have plain brown wings (ww).There are no new mutations indivisuals mate randomly, and there is no natural selection on wing color.Explain , why any calculation, wether this population is under a hardy weinberg equilibrium
About the question:
I failed to find the complete question. However, I will explain why this population is considered to be in Hardy-Weinberg equilibrium, and what the destiny of the alleles is.
Answer:
This population is in equilibrium because it accomplishes all the H-W assumptions for a population in equilibrium. Genetic nor allelic frequencies will change generation after generation. Alleles will remain equal.
Explanation:
Available data:
A single gene controls wing colorHalf of the moths have white-spotted wingshalf of the moths have plain brown wingsW allele is dominant and expresses white wingsw allele is recessive and expresses brown wingsIndividuals mate randomlyNo natural selectionWe will know by theory if this population is or is not in equilibrium Hardy-Weinberg if the population is in concordance with the assumptions of the theory. So let us first analyze the Hardy-Weinberg assumptions for a population in equilibrium:
• Random matings: Any individual get crossed with any other individual
• No superposed generations: each individual can leave their gametes in the pool only once.
• No mutations: No mutations originate any new gametes.
• No migration: No incorporation of gametes from other populations.
• Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.
• No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
So, the exposed population
- is isolated, meaning that there is no gene flow from other populations. No new genes will be introduced.
- has no mutations, so no allele will change to express a new form
- individuals mate randomly
- there is no natural selection acting on this group as an evolutive force that might alter the equilibrium.
Genetic nor allelic frequencies will change generation after generation.
In a Hardy-Weinberg population, where allelic frequencies are p and q (assuming a diallelic gene), genotypic frequencies after one generation of random matings are p², 2pq and q². The allelic frequencies, as well as the genotypic frequencies, remain equal after successive generations. Alleles will remain in the population from many generations.

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.
B.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again. They find that the colder temperature showed a high pressure in the tires and that the pressure decreased after the tires were able to warm up.
C.
The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.
D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.

Each one of the boxes on the Punnett square represents what probability of a offspring genotype?
A-10%
B-0%
C-1%
D-25%
Answer: D - 25%
Explanation:
There are four boxes in this punnet square, each one an equally possible genotype for the offspring.
Each box then has a 1/4 (25%) possibility of being the offspring's genotype.
Each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.
What are a punnet square and its uses?Every possible outcome of a genetic cross between two individuals with known genotypes is listed in the Punnett square, a table. In its simplest form, the Punnett square is a square divided into four quadrants.
A Punnett square can be used to determine the expected frequencies of various genotypes in the children of two parents. A Punnett square can be used to forecast the percentages of phenotypes that will come from known genotypes in a cross' offspring.
Thus, each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.
