answer explanation:
All group 16 elements combine with hydrogen to form hydrides. Acidic nature and bent shape decrease from water. The H-E bond length increases as the bond dissociation enthalpy decrease down the group. Thermal stability and reducing character also decreases because the H-E bond length increases down the group.

Plants manufacture their own supplies of carbohydrate. What are the raw materials and the waste product of this process? raw materials waste product A. Carbon dioxide and chlorophyll oxygen. B. carbon dioxide and water oxygen. C. oxygen and chlorophyll carbon dioxide. D. oxygen and water carbon dioxide.
Answer:
Carbon dioxide, water, and sunlight are the raw materials for photosynthesis. Photosynthesis is the process by which green plants make their own food from carbon dioxide and water in the presence of sunlight. The prepared food is glucose. To prepare one molecule of glucose, by the process of photosynthesis six molecules of carbon dioxide and six molecules of water is required. Six oxygen molecule is released as a byproduct.
Thus, the correct product are 'Carbon dioxide, water, and sunlight'.

According to the food web, how many primary consumers are indicated?
Select one:
O a 2
O b. 1
O c.3
O d.4
Answer:
C. 3.
The grasshopper, rabbit, and mouse are all primary consumers. A primary consumer is an organism that consumes producers (plants/primary producers). A primary consumers only eat plants and dont eat any meat so the grasshopper, mouse, and rabbit would be the three only primary consumers.
Hope this helps! :D
As per the food web, the number of primary consumers is 3. The correct option is c.
A food web is a sophisticated network of linked food chains that represents the movement of nutrients and energy within an ecosystem. It exemplifies how various organisms in a society rely on one another for survival.
Herbivores, usually referred to as primary consumers, are very important to the food chain. They are organisms that consume plants or compounds derived from plants directly.
They act as a link between lower-level consumers (plants) and more affluent ones (predators). Rabbits, deer, cows, and other insects are a few examples of primary consumers.
Primary consumers use plant materials to get energy, but they also help control plant populations, affecting the ecosystem's general stability and balance.
Thus, the correct option is c. as it is having 3 primary consumers namely rabbit, grasshopper, and mouse.

How many oxygen molecules can one hemoglobin carry.
Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Answer:
Oxygen binds reversibly to harem, so each hemoglobin molecule can carry up to four oxygen molecules. Hemoglobin is an allosteric protein; the binding of oxygen to one harem group increases the oxygen affinity within the remaining harem groups.
A sample of DNA contains 120 nucleotides, if 35 nucleotides are Guanine, how many nucleotides are Thymine?
(If you can show how you do it that would be great)
Answer:
25
Explanation:
In DNA, Guanine pairs with Cytosine, and Thymine pairs with Adenine. This tells us that there are equal numbers for each Guanine and Cytosine, and Thymine and Adenine. When there's 35 Guanine, there should be 35 Cytosine that goes with it. 120 - 2(35) = 50. The remaining 50 nucleotides are Thymine and Adenine, and since they are the same number, divide 50 by 2. 50 ÷ 2 = 25. There are 25 thymine in the sample of DNA.

Answer:
C
Explanation:
Being on the coast will result in milder temperature fluctuations because the nearby body of water helps regulate any big changes a city might occur. Being near the coast where lots of water is evaporating and forming clouds which then move inland and precipitate or rain, often fairly close to shore.
