Answer:
Annual plants live for one growing season and then die, while perennials regrow every spring. ... The difference, according to plant geneticist Siegbert Melzer and his team, comes down to two critical flower-inducing genes that, when turned off, can make an annual plant regrow every year.

explain how ATP can be compared to a rechargeable battery.
Explanation:
when it's fully charged it's a ATP and when it's runs down it's ADP
and there are times when the cells need more energy and splits off another phosphate so it goes from ADP adenoside di-phosphate, to AMP, adenosine mono-phosphate
and there you have it
The nucleus has a system of _____ embedded within its outer membrane which allows communication between the nucleus interior and the cytoplasm.
Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by nuclear pore complex. It allows the pore to regulate the movement of molecules between the nucleus and the cytoplasm. It allows small particles to pass through such as ribosomal proteins. It prevents most large particles (except for histone) from passing through; thus, it is selective in nature. This function of the pores clearly shows that it allows communication to occur between the nucleus interior and the cytoplasm.

what did Miescher contribute to the discovery of DNA? When was this discovery made?
Answer:
Explanation:
In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.

what is the effect of soil salinization on crops?
Answer:
Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Answer:
A. The equation for photosynthesis and cellular respiration are opposites of each other.
Explanation:
Cellular Respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis:
6CO2 + 6H2O → C6H12O6+ 6O.
Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.

Answer:
B. From 200 m to the surface
Explanation:
Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.
In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.
Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.
Which of these actions would people in a location in Florida most likely take if the local

People should take shelter in an interior room without windows in a location in Florida most likely take if the local weather forecast predicts a tornado.
What do you mean by tornado?A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud.
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms.

of Raul's car.
In this equation, a is acceleration, Vf is the final velocity, v; is the initial

Explanation:

Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.
Let us assume that following:
S=distance
U=initial velocity
V=final velocity
A=acceleration
T=time taken
Given that:-
S=2.5 km
S=2.5×1000 mtr
S=2500 mtr
T=12 seconds
V=180km/hr
=180×1000/3600 m/sec
V=50 mtr/sec
U=0 because in starting his car in rest position
Equation which use for calculations of acceleration,
S = UT + 1/2AT^2
2500 = 0×12 + 1/2A(12)^2
2500 = 0 + 1/2×A×144
2500 = 72×A
A = 2500/72
A = 34.72 m/sec^2
It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2
