What two input for Photosynthesis that plants use to make their food is
O Light energy, H20 (water)
O Light and Oxygen
0 Light and ATP
Answer:
Light energy and water
Explanation:
Answer:
Light energy and H20
Explanation:
Plants use the energy from the sun and water to grow to create things like oxygen as well as things like glucose. It cannot make oxygen out of oxygen because then it wouldn't need to be made by plants. ATP is energy that is made during cellular respiration, cellular respiration uses the oxygen and glucose produced by plants during photosynthesis to create ATP energy.

Which statement describes an advantage of asexual reproduction?
Asexual reproduction results in variations in DNA.
Asexual reproduction causes less competition for resources.
O Asexual reproduction is faster than sexual reproduction.
O Asexual reproduction requires more energy than sexual reproduction.
Answer:
i would pick the answer c
Explanation:
sexual reproduction is slower than asexual reproduction because in order to reproduce sexually, you would need to find a partner first. but reproducing asexually is quicker because you don't need a partner
Answer:
c or b
Explanation:
asexual reproduction is much faster and lots of resources are not needed. while sexual reproduction you need another parent .
Assume that conditions in Paxton Lake, including the availability of benthos and zooplankton and the number and type of predators in the benthic and limnetic zones, remain unchanged. If you returned to Paxton Lake in a thou- sand years and collected data about the mating choices of benthic and limnetic sticklebacks and the proportions of benthic, limnetic, and hybrid sticklebacks in the lake, what would you expect to find
Answer:
The sticklebacks will remain a single species
Explanation:
When species leave in an area with favorable conditions, it feeds and reproduces freely, and when these conditions (availability of food, predator population) remain unchanged for a long period of time, the specie's physiology and habits would also remain unchanged (there would be no speciation).

Answer: Excretion is the removal from the body of waste products which result from normal life processes. Waste products such as carbon dioxide must be removed. If they are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.
Answer:
B. The genetic variation for the trait was exhausted.
Explanation:
Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.
8) Outline what you would need to know to answer the following question: of all the proteins that exist on earth at this time, what fraction of them have a known structure
Answer:
To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data
Explanation:
The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.

The tectonic plate boundaries, rocky material brought to the Earth's surface from its interior and from the Earth's surface to its interior. So, the correct option is A.
What are Tectonics plates?Tectonic plates are defined as huge pieces of Earth's crust and uppermost mantle that are made up of oceanic crust and continental crust. Earthquakes occur around major faults that mark mid-ocean ridges and plate edges.
These plates act like hard and rigid shells in comparison to Earth's mantle which is the strong outer layer called lithosphere. At tectonic plate boundaries, rocky material is brought to the Earth's surface from its interior and from the Earth's surface to its interior.
Therefore, the correct option is A.

Describe both fractions of protein constituting gluten and explain how each contributes to the behavior of gluten in batters and doughs.
Answer:
Gluten contains gliadin and glutenin. Glutenin is elastic and is responsible for the elasticity in doughs and batters. The gliadin fraction is a monomeric protein, the presence of high gliadin makes dough and batter more rigid.
Explanation:
The gluten protein has two fractions of gliadin and glutenin, both of which have culinary values. The more glutenin in wheat used for baking, the more elastic the dough becomes while more gliadin makes dough and batter less elastic.

What would most likely happen to plant cells if the plant was watered with salty water?
A. Water will enter the plant cells until the large central vacuole bursts
B. The plant's root will filter out the right amount of salt so the plant can remain isotonic.
C. Salt crystals will form on the leaves as water evaporates on the leaf surface.
D. Water would leave the large vacuole of the cell and the plant will droop.
Answer:
option D
Explanation:
the plant will lose water because water moves out of the cell and the vacuole will leave the cell
Water would leave the large vacuole of the cell and the plant will droop if it was watered with salty water.
What is Vacuole?This is referred to as an organelle within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid.
In cases where the plant is watered with salty water, osmosis takes place which involves water leaving the vacuole and the plant drooping thereby making option D the most appropriate choice.

Hydrogen - 3 is a radioisotope with a half life of 12.32 years. How long would it take a 40 g sample to decay down 2.5 g ?
Answer:
Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.
Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium. After another 12.3 y—now a total of 36.9 y—another half of the remaining tritium will have decayed, leaving 12.5 g. This sequence of events is illustrated in Figure 15.1 “Radioactive Decay”.

What is sea-floor spreading ?Seafloor spreading is mainly caused by tectonic activity that is constantly occurring within the tectonic plates of the Earth.
Tectonic plates are moving because they are situated on the crust of the Earth, which lies on top of a partially molten layer of rock, called the asthenosphere.
Tectonic plate movement is responsible for the formation of natural landmarks such as mountains and volcanoes, and natural disasters such as earthquakes.
