What term describes DNA sequences that determine specific physical traits?
A. Genes
B. Nucleus
C. Genome
D. Chromosomes
You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the cell. What is the best explanation for this observation?
a) the cell has just gone through the S –phase of the cell cycle so there is double the amount of DNA
b) the cell has just gone through telophase but not cytokinesis
c) the cell has gone through meiosis I and is preparing for meiosis II
d) the cell is in G1 and is preparing for DNA synthesis
Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
Chromatids, which are chromosomes, are found in the cell poles. It initiates the formation of the nucleus membrane. The chromosomes begin to turn into chromatin. Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.
c. A somatic cell does not experience meiosis.

Which displays Earth's curved surface on a flat model?
globe
grid
meridian
projection
Answer:
d
Explanation:
Globe displays Earth's curved surface on a flat model.
What is Globe?It's clear that whoever said "it's a small world" has never attempted to leave it. In actuality, the size of the globe is rather astounding, and figuring out just how massive it is took many thousands of years.
Our estimations have evolved over time, from astronomers discovering that the Earth was round (and not a flat disc, cube, or ziggurat) to the first successful attempts at circumnavigating the planet.
And the development of modern astronomy, together with advancements in science and the ability to see Earth from space, has undoubtedly been helpful.
Therefore, Globe displays Earth's curved surface on a flat model.

What occurs during stage two of photosynthesis? Carbon dioxide enters the stomata. Sunlight strikes the leaves. Energy is captured in the chloroplasts. Chlorophyll absorbs light.
Answer:
Stage two: carbon fixation
The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar. The reactions of carbon fixation are controlled by specific enzymes.

. Fossil fuels are formed in the geological past from the remains of living organisms. Petroleum products, such as coal and natural gas are considered fossil fuels. Why are these types of fuels considered NONrenewable?
Answer:The types of fuels are considered non renewable because you could run out of the fuels quickly, but it would take over a million years just to renew the fuel
Explanation:
The types of fuels are regarded as non-renewable since they might swiftly run out while taking over a million years to replace them.
What are non renewable resources?Non renewable resources are defined as a natural resource that cannot be easily replaced by other natural processes quickly enough to meet demand. Coal or natural gas waste results from the use of non-renewable energy sources. This necessitates increased energy use and environmental protection.
The components of fossil fuels are decaying plants and animals. We rely on those fuels to heat our houses, operate our cars, supply electricity to us, and power manufacturing and industry. Since the creation of fossil fuels requires hundreds or millions of years, they are regarded as non-renewable resources. They cannot be instantly reused after being used.
Thus, the types of fuels are regarded as non-renewable since they might swiftly run out while taking over a million years to replace them.

Answer:
I think domain or family but I think domain more.
Explanation:
One domain in that phylum of animals is mammals, which includes lion and howler monkeys.
What is domain?
A taxonomic rank called a domain is used to categorize living things. A domain is the highest level of classification in biology, just below a kingdom. Eukarya, Bacteria, and Archaea are the three domains. Eukarya are multicellular organisms, whereas Archaea and Bacteria are single-celled.
On Earth, life can be found in four different domains: the domains of bacteria, archaea, eukarya, and viruses. Each domain has its own distinctive qualities. Single-celled organisms without a nucleus are known as domain bacteria.
