through repeated rounds of meiosis.
True
False
Answer:
False
Explanation:
we create more body cells with mitosis not meiosis , we create gametes with meiosis
Which of the following best describes the matter present in an ecosystem?
A.
New matter is continuously generated by an ecosystem in a process known as photosynthesis.
B.
The waste materials generated by one organism are often reused by other organisms.
C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.

If a housefly had 6 chromosomes would the cell be diploid or haploid
If a human have 23 chromosomes would it be a gamete or a somatic cell?
Why is the chromosome number in each of the animal cells an even number?
Answer:
If a housefly had 6 chromosomes would the cell be diploid or haploid?
Haploid
if a human have 23 chromosomes would it be a gamete or a somatic cell?
Gamete
Why is the chromosome number in each of the animal cells an even number?
Even numbers could be divided by 2 evenly

List two advantages for synthetic fertilizers
Answer:
Cheaper to purchase than organic
Nutrients are concentrated, only small amounts needed
Nutrients are quickly available for plant absorption
Answer:
They're faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.
Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents? Show the Punnett Square to prove it.
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.

What health and environment factors negatively impact the flow of blood through the body?
Answer:
Certain types of Air pollution, Diseases
Explanation:
Environmental factors
Carbon monoxide is produced when fuels such as gas, oil, coal and wood do not burn fully. The increase of factories and manufacturing stations globally increases the chances of one inhaling carbon monoxide. When inhaled the carbon monoxide binds the haemoglobin in the blood increasing the chances of heart failure and brain damage.
Health factors
Health conditions such as Obesity, Diabetes can contribute to poor blood flow in the body. If someone were to suffer from obesity they would consequently have fatty deposits in the lining arteries. These deposits shrink the space that blood can pass through arteries. This means the heart has to pump blood harder to achieve the same task as someone able bodied. This dangerous because the heart would be at more risk of failing under the strain of the excess mass.

Describe the order of succession for the regrowth of
the fire destroyed forest.
Explanation:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]
Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
Primary succession on Rangitoto Island
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]

what does the following types of algae is uni cell
ular
Answer:
Most often there is a unicellular alga chlamydomonas. It moves in water with the help of two flagella located on the front, narrower end of the cell. Outside the chlamydomonas is covered with a transparent membrane, under which there is a cytoplasm with a nucleus, a red "eye" (a photosensitive body of red color), a large vacuole filled with cell juice, and two small pulsating vacuoles. Chlorophyll, contained in the chromatophores, gives a green the cell a green color.

Explain what direct evidence is used to help geologists learn about earths interior
Answer:
Seismic Waves.
Explanation:
Geologists record the seismic waves and study how they travel through Earth. Different types of seismic waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. Using data from seismic waves geologists have learned that Earth's interior is made up of layers.
