if photosynthesis stopped?
Reservoirs of the carbon cycle will have more Carbon stored.
What is photosynthesis?Photosynthesis is the process in which green plant produce their own food using carbon dioxide and water.
Carbon dioxide contributes to carbon cycle and when plants do not use carbon dioxide, Carbon will remain stored in the atmosphere in large quantity.
Therefore, Reservoirs of the carbon cycle will have more Carbon stored.

A few minutes of incubation at room temperature in the laboratory will inactivate HIV, but the flu virus is still active after incubating for several hours. What are the practical consequences of these findings?
Answer:
Flu virus cause more infection than HIV virus.
Explanation:
The practical consequences of these findings indicates that the flu virus has more chances to cause infection in the person due to its active nature as compared to HIV virus which is inactive after incubation. This active nature of the flu virus results in the infection of more people in the world as compared to HIV patients so we can conclude that flu virus is more common than HIV virus due to its activeness.
Which of the following are contributions of deforestation to global climate change? Select all that apply.
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Clearing of forests increases the leaching of nutrients in affected regions.
Deforestation increases the risk of landslides in cleared regions.
Answer:
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
First of all, deforestation is the conversion of forests to non-forest uses. Non-forest uses include agriculture, industrial development, infrastructural development, etc.
Forests are sinks for carbon and their removal or conversion to non-forest uses means that less carbon would be fixed through photosynthesis. Slash and burn agricultural practice also leads to the emission of carbon dioxide into the atmosphere.
Thus, more carbon dioxide would be present in the atmosphere as a result of deforestation and burning. This carbon dioxide is a greenhouse gas that causes the warming of the planet, a phenomenon that results in the change of climate of the planet.
Hence, the conversion of forest to cropland leading to a decrease in the rate of carbon fixation and the emission associated with burning both contribute immensely to global climate change.

The bones makes up the musculoskeletal system of the body. It provides framework of the body and gives attachment to muscles and tendons.
There are two types of bones:
The compact bone: This makes up about 80% of the body bone mass. It is made up of a large number of tube-shaped units called osteons. The way the osteons are aligned in the bone, gives it great strength.The cancellous bone: This is also called spongy bone. This is because it looks like a honeycomb. There are presence of little beams called trabeculae which consists of a few lamellae and osteocytes interconnected by canaliculi.Learn more here:

In the soybean respiration experiment, why were glass beads added in the non-germinating seed tube?
Answer:
Explanation:
The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube. The respirometer with just the glass beads served as a control, allowing changes in volume due to changes in atmospheric pressure and/or temperature.
The purpose of the beads is to ensure that each respirometer is uniform in volume. The vial with glass beads alone will permit detection of any changes in volume due to atmospheric pressure changes or temperature changes.

red and white spotted flower if you cross a spotted flower with a white flower?
The chances of getting a red and white spotted flower if you cross a spotted flower with a white flower are - 25%.
CodominanceThis is an inheritance pattern in which both the alleles of a gene are expressed in an organism. In the camellia plant, alleles R and allele W will express themselves independently of each other.
Due to this, in heterozygous condition (RW) the phenotype appears as a hybrid that is presence of red and white patched flowers.
Crossing: a spotted flower (RW) with a white flower (WW)

What is Codomince?In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person. That is, both qualities emerge rather than one trait predominating over the other, as in a plant or animal with multiple pigment colors.
One common characteristic of people that you can't really see just by looking at them, but that many people are aware of, is their blood type.
One A allele and one B allele are present in individuals with the blood type AB. Their blood type is AB because both alleles are expressed simultaneously.

How is the DNA sequence AATTA replicated in a new strand during semiconservative replication?
Answer:
According to the semi-conservative DNA replication, the AATTA sequence is transcribed into a new strand as TTAAT, taking into account the complementarity of nitrogenous bases.
Explanation:
Semi-conservative DNA replication means that two molecules are obtained from a double-stranded DNA molecule, each with an original strand and a new strand.
The DNA is composed of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G≡CThen, for the sequence AATTA of the strand DNA mold, the sequence on the new strand would be complementary, i.e., TTAAT.

Having freckles is a dominant trait, and not having freckles is a recessive trait. Which set of parents will not have any children with freckles? A. A mother with FF and a father with ff O B. A mother with Ffand a father with Ff O c. A mother with ff and a father with ff
As freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait, i.e., ff. The correct option is C.
What are recessive traits?Recessive trait is a trait that really should be transmitted by both parents in order to be present in the offspring. Recessive features might exist in a person's DNA but not manifest in that individual.
As in the given case, F denotes dominance, and f denotes recessive character. Dominant trait always superimpose over the recessive one.
So, as freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait i.e., ff.

Oxygen has 6 valence electrons. How many electrons does an atom of oxygen need to become stable?
two
four
six
eight
Answer:
2 electrons
Explanation:
According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.
Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.
