Answer:
The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.
Explanation:
Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

Y ir instrumentos de laboratorio usaron luis y Juan?
Luis y Juan querían hacer una investigación sobre la rapidez de disolución de una pastilla efervescente en el ácido acético a temperatura caliente. Para esto, tenían que triturar la pastilla y luego utilizar solamente 15 gramos de la sustancia. Tenían que medir 50 ml de ácido acético y colocar el mismo en un recipiente donde se pueda calentar sustancias, pero que el vapor generado se libere rápido. Al agregar ambas sustancias al recipiente de vidrio, lo comenzaron a calentar. Una vez se iba calentando, agitaron las sustancias poco a poco y con mucho cuidado, tomaron los cambios en temperatura de cada 2 minutos. Al finalizar el experimento, ellos compartieron sus resultados con sus compañeros de clase.

explain the effect enzymes have on chemical reactions
Answer:
Enzymes decrease the activation energy, Enzymes increase the rate of the reaction, Enzymes provide a site where reactants can be brought together.
Enzymes are like catalysts which enhance the rate of reaction by lowering the activation energy.
All the biochemical reactions are slow because of transition state barriers. These transition state barriers are an intermediate state before the formation of products. Transition state is a high energy state and it requires a lot of energy to cross this state but we can not produce this much energy in our body. That is why an enzyme is must to catalyze any bio-chemical reaction because enzyme provides an alternate pathway which requires very low energy to proceed.
Enzymes have certain active sites wherein substrates fit in and interact with each other with the help of their functional groups and interaction of these substrates subsequently leads to product formation.

Distinguish among corms, bulbs, and tubers.
Answer:
Bulbs
Bulbs are plant storage organs generally grown underground, consisting of a short stem ( the basal plate ), from which grow overlapping, swollen leaves or leaf bases. The top growth emerges from the bulb center. Here's an example : See the attached photo.
Corms
Corms are not made up of leaves, but a vertical swollen compact stem, and as such are solid. The corm is protected by a tunic of old leaf petioles. Here's an example :See the attached photo.
Tubers
Tubers are, simply, enlargements in the underground stem or lateral root of a plant that are used for food storage. These vary greatly in appearance, but all have the same function. Here's an example : See the attached photo.
Look at the picture of different food groups. Which two groups are mainly eaten for their energy? Add up the numbers and give the answer. For example, if you think it is 4 and 3, you would write 7, because 4 + 3 = 7.

Explanation:
The cells in this leaf are making their own energy by the process of
a
respiration, where oxygen and sunlight at Q and R are taken in and then converted into carbon dioxide and glucose at S and T.
b
photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
c
photosynthesis, where glucose and oxygen at Q and R are taken in and then converted into water vapor and thermal energy at S and T.
d
respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and methane gas at S and T.
Answer:
B is the answer. Glucose and oxygen are given off during Photosynthesis
The cells in this leaf are making their own energy by the process of photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP.
Photosynthesis is critical for the existence of the vast majority of life on Earth. It is the way in which virtually all energy in the biosphere becomes available to living things.

A student made a model of an onion skin cell she viewed
using a microscope. The scale is 500:1. The student's cell
model has a length of 15 cm.
How many centimeters is the real cell's length?
A. 7500 cm
B. 0.002 cm
C. 33 cm
D. 0.03 cm
If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm
