Answer:
Carbon dioxide, water, sunlight.
Explanation:
Photosynthesis uses the energy in sunlight to drive the reactions that produce glucose. These reactions are necessary for the algae to produce food, continue to survive, and grow.
As well as sunlight, photosynthesis requires carbon dioxide and water as reactants. The reaction produces glucose and releases oxygen as a byproduct.
The algae need an adequate supply of all of these reactants to grow in abundance.

An important piece of information in the management of a person infected with a chronic virus such as HIV is his/her "viral load" or how many virus particles can be detected. If before PCR, a patient had a viral load of 1.6 x 104 viral particles. What would be the amount of DNA in the sample after the completion of the first PCR cycle?
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
At what time of day is surface temperature highest? Lowest?
Answer:
the highest temperature is at around 2230 UTC or 4:30 (1630) in the afternoon, local standard time. The lowest temperature is around 7 in the morning local standard time. Did you expect the temperature to be warmest at noon, when the sun is highest in the sky
Explanation:
What determines how much total kinetic energy something has?
What determines how much total kinetic energy something has is the mass and speed of the object.
The kinetic energy of a substance is the energy possessed by the substance due to its motion.
The formula for calculating kinetic energy is given as;
K.E = ¹/₂mv²
where;
m is the mass of the objectv is the speed of the objectThus, we can conclude that what determines how much total kinetic energy something has is the mass and speed of the object.

Why might the xiphoid process be missing from the sternum in a set of human remains?
Answer:
Why might the xiphoid process be missing from the sternum in a set of human remains? The remains are from an adult younger than 40 years of age, and the hyaline cartilage does not preserve as well as bone. Because the xiphoid process may be broken off if the individual had been given CPR.

If a nucleus has eight chromosomes during interphase, how many chromosomes does it have after mitosis is complete
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
Which of the following correctly describes distinguishing characteristics of the Kingdom Plantae?
O Photosynthtic and multicellular
O Vascular and flowering
O Prokaryotic and photosynthetic
O Terrestrial and eukaryotic
Photosynthtic and multicellular correctly describes distinguishing characteristics of the Kingdom Plantae.
What are the characteristice of kingdom Plantae?Kingdom Plantae includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis.
They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes.
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).

In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant.
Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllele but it can still be passed on through generations. Imagine a female is a carrier for hemophilia; her genotype is XHXh. She is married to a man who does not have hemophilia. What conclusion is NOT valid concerning this genetic cross?
A) 0% of female offspring will have hemophilia.
B) 100% of the male offspring will have hemophilia.
C) There is a 50% chance that male offspring will have hemophilia.
D) The chance that female offspring will have the allele for hemophilia is 50%.
Answer:
B isn't valid
Explanation:
As you observe from the diagram above, the second offspring (a male) doesn't have haemophilia disproving option B

explain how energy from sunlight is used during photosynthesis, then how the energy is transferred to animals that cannot harness energy directly from the sun.
help me please
Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria. ... The energy cycle for life is fueled by the Sun.

Explain why red blood cells can be maintained in an intact state by keeping them in a normal saline solution.
Answer:
The solution is isotonic.
Explanation:
Saline solututions are mixtures of salt and water. In a normal saline solution, red blood cells maintain their shape. This is because the saline solution is isotonic. Essentially it has the same concentration as inside the red blood cell.
The water does not move down a particular gradient, thus the shape remains unchanged.
Red blood cells can be maintained in an intact state by keeping them in a
normal saline solution because the solution is Isotonic.
Isotonic solutions possesses the same osmotic pressure or equal
concentration of solutes and this aids free movement of solute in and out of
the cell via the semi-permeable membrane.
The solution must be isotonic to enable the red blood cells remain intact
thereby preventing swelling or shrinking of the cells.

Answer:
D) Hemoglobin
Explanation:
The part of the blood that carries oxygen is hemoglobin.
What is Hemoglobin?The amount of hemoglobin in your blood can be measured using a hemoglobin test. Red blood cells include a protein called hemoglobin, which distributes oxygen to your body's organs and tissues while returning carbon dioxide to your lungs.
A low red blood cell count indicates a low hemoglobin level, which can be determined by a hemoglobin test (anemia). Vitamin deficiencies, hemorrhage, and chronic disorders are just a few of the numerous potential causes of anemia.
If a hemoglobin test reveals a higher-than-normal level, there are a number of possible explanations, including the blood condition polycythemia vera, high altitude living, smoking, and dehydration.
