• the discovery in the 1960s of cosmic microwave background radiation.
1. Hubble’s discoveryin 1924 astronomer Edwin Hubble used a technique pioneered by Henrietta Leavitt to measure distances to remote objects in the sky.Hubble used spectroscopic red-shift data to measure the speeds these objects were travelling then graphed their distance from Earth against their speed.He discovered that the speed at which astronomical objects move apart is proportional to their distance from each other2. discovery in the 1960s of cosmic microwave background radiationOn May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB)It states that the ancient light that began saturating the universe 380,000 years after its creation.It also supports the big bang theoryThus, Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.

What phase does not occur between meiosis I and meiosis II, which results in haploid daughter cells?
Answer:
A. Interphase
Explanation:
Interphase happens to the cell before meosis 1.
Answer:
Meiosis II may begin with interkinesis or interphase II. This differs from interphase I in that no S phase occurs, as the DNA has already been replicated. Thus only a G phase occurs. Meiosis II is known as equational division, as the cells begin as haploid cells and end as haploid cells.

Both anaerobic and aerobic respiration use
to produce ATP and NADH. In anaerobic respiration, NADH is regenerated to NAD+ by
, while in aerobic respiration, electrons from NADH are deposited in the
to regenerate NAD+. Anaerobic respiration produces
ATP per molecule of glucose compared to aerobic respiration.
Answer:
1. glycolysis
2. fermentation pathways
3. electron transport chain
4. less ATP
Explanation:
Cells employ two distinct metabolic processes, anaerobic and aerobic respiration, to generate energy in the form of ATP and NADH. While in aerobic respiration, electrons from NADH are deposited in the electron transport chain to renew NAD+, in anaerobic respiration, NADH is converted to NAD+ via fermentation.
What is the scenario with the fermentation ?The process of fermentation, which is anaerobic (does not require oxygen), is utilised to produce NAD+ from NADH. In this metabolic process, the pyruvate that results from glycolysis is converted into other molecules like ethanol or lactic acid.
So that glycolysis may proceed, NADH is reverted to NAD+ as part of the process. Per molecule of glucose fermented, two ATP molecules are created as the final result.
As opposed to this, aerobic respiration is an oxygen-dependent procedure that yields a lot more ATP than fermentation does. This is so that aerobic respiration, which creates a proton gradient across the inner mitochondrial membrane by transferring electrons from NADH to oxygen through the electron transport chain, can take place.
The ATP synthase enzyme, which generates ATP from ADP and inorganic phosphate, is propelled by this proton gradient. So that glycolysis may proceed, NADH is converted during the process into NAD+.
Per glucose molecule, aerobic respiration results in the production of 38 ATP molecules. Anaerobic respiration generates two ATP molecules for every glucose molecule, but aerobic respiration generates 38 ATP molecules for every glucose molecule.

Explain how cellular respiration and photosynthesis work together in plants.
Answer:
teamwork makes the dream work
Answer:
Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis:
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2

The only cells that do not have 23 pairs of chromosomes are the mature sex cells is a true statement and contains 22 pairs of autosomes and 2 sex chromosome.
What is gametes?Gametes are the haploid cells produced by the reproductive organ, by the process of meiosis, reproductive organ produce the haploid cells.
These gametes are also known as mature sex cells, having haploid set of chromosome, when female gamete and male gamete are fertilized the resultant zygote is diploid.
In human karyotype, they include autosomes and sex chromosome, autosomes are common in both male and female, but in female there are 22 pairs of autosomes and XX are sex chromosome, while in male 22 pairs of autosomes and XY are sex chromosome.

Hypoxic environments have very little oxygen in them. In the most extreme cases,
they may have no oxygen at all. What process must cells in these environments use to
get the energy needed for life processes out of the food molecules they take in?
A photosynthesis C. anaerobic respiration
B. aerobic respiration D. Osmosis
Answer:
The process cells must use in hypoxic environments to obtain energy from the food molecules they take in is anaerobic respiration (option C).
Explanation:
Anaerobic respiration is the process of energy production that cells carry out in the absence of oxygen. This type of reaction requires an electron acceptor other than oxygen.
Some microorganisms, such as bacteria, can carry out their metabolism in environments with little or no oxygen. In these organisms, the energy-producing pathways are anaerobic respiration and fermentation reactions.
The other options are not correct because:
A. Photosynthesis: occurs in plants, and is based on the conversion of solar energy into chemical energy.
B. Aerobic respiration: requires the presence of oxygen, the final electron acceptor of the electron transport chain.
D. Osmosis: is a transmembrane transport mechanism.
The function of a virus?
the function of a bacteria?
Answer:
the function of a virus is to deliver its genome into the host cell to allow its expression by the host cell. It will, at least attempt to, take over the body and infect the body with the disease virus on it.
the function of a bacteria can be good or bad. for good purposes for example, would be the digestive bacteria that breaks down the food and uses the energy to give the body energy. the bad version of bacteria is to spread from surface to surface, like the flu for example.

When economic conditions are favorable, more effort can be put into synthetic materials that satisfy desires and not just needs.
O True
O False
Answer:
True
Explanation:
The correct answer would be true.
A favorable economic condition in an area means that a large percentage of the population of the people in the area already have their basic needs met. According to Abraham Maslow, when basic needs are met, human needs graduate from basics to more sophisticated ones. Consequently, production efforts can be put into producing material that satisfies desires and not just needs.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.
Explanation:
An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.
