Answer: Consumer

Explanation:

Consumers are the organism that feed on the producers for their energy source.

The producers are the green plants that make food by the help of the process known as photosynthesis.

The consumers feed on the plants for their energy need(primary consumers).The animals that feed on small animals for their energy needs are known as secondary consumers.

Here, the hawk feed on woodpecker so it is secondary consumer.

Identical copies of chromatin held together by cohesin at the centromere are called _____.
Amanda [17]

Answer:

Sister chromatids.

Explanation:

Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.

The girl is suffering from osteopenia.

The osteopenia is a condition, in which the bone mass of the person is significantly reduced. High amount of training and less intake of fats may cause a decrease in the hormone estrogen in young girls. this decrease in the hormone may lead to the irregular periods as well as decrease in bone mass, which eventually causes osteopenia. the osteopenia is a precursor of the osteoporosis, the osteopenia later, if untreated causes a further decrease in bone mass and porous bone (osteoporosis).

Compare and contrast the two types of rainforests. Be sure to include information for both biotic and abiotic factors.
kolbaska11 [484]
The ecosystem of the forest is formed by the interaction between the abiotic and biotic factors. Abiotic factors are the non-living factors: water, temperature,light,cloud cover, and soil. Biotic factors oh the other hand are the living organisms. Tropical rain forests<span> are hot, moist forests found near Earth's equator.</span>
Temperate rain forests are cool and dry.
Abiotic factors in temperate rain forest:
1. Temperature:The climate in the temperate rain forests is mild.
2. Water: moist and lush.
3. Light: many clouds block the sunlight.
4. Soil: nutrition rich.
Biotic factors:<span>beavers, raccoons , cougars and black bears. </span>

Abiotic factors in tropical rain forest:
1. Temperature: hot, near the Earth's equator
2. Water:60 to 160 inches of precipitation

Biotic factors: the greatest biodiversity in the world<span>,
 rubber and bamboo trees, sloths, anteaters, poison dart frogs, </span>

Hemoglobin transports oxygen in the blood and consists of a chain of 146 amino acids. how many different types of amino acids ar
ddd [48]

Solution:

Myoglobin has a single chain of 153 amino acids wrapped around a group of iron and other atoms (called "heme") to which oxygen binds. Hemoglobin, in contrast, is made of up four chains: two identical chains consisting of 141 amino acids, and two other identical chains consisting of 146 amino acids.

Because amino acids can be arranged in many different combinations, it's possible for our body to make thousands of different kinds of proteins from just the same 21amino acids. There are only 20 amino acids.

The 20 Amino acids which make proteins are:

• alanine - ala - A (gif, interactive)

• arginine - arg - R (gif, interactive)

• asparagine - asn - N (gif, interactive)

• aspartic acid - asp - D (gif, interactive)

• cysteine - cys - C (gif, interactive)

• glutamine - gln - Q (gif, interactive)

• glutamic acid - glu - E (gif, interactive)

• glycine - gly

what were some of the strange and unexpected things that scientists discovered when they analyzed the human genome? (the video)
OlgaM077 [116]

<span>Before the completion of the Human Genome Project, it took few years before the well-known forecasts stated that humans had at least 100,000 genes. But latest Human Genome Project evaluates lowered number to a more timid range of 20,000 to 25,000. It has helped to narrow the range of feasible genes and to separate certain candidates as supplying to particular diseases. Scientists have also re-evaluated past conclusions, such as the idea that genes are self-restrained, detached pieces of DNA with defined character. They now know that some genes that tasks simultaneously can make more than one protein; where in fact the average gene might make three proteins. Also, genes will be visible to grab genetic code from other DNA parts</span>
