Where do most volcanoes form?
A. Near plate boundaries
B. In the middle of tectonic plates
C. Where there is no plate movement
D. On a supercontinent
Explanation:
Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. ... Sometimes, the plates collide with one another or move apart.
What step in photosynthesis may occur during day and night? A.Light independant reactions B.Light dependant reactions c. Photolysis
Answer:
a is the answer
Explanation:
Light independent reactions of photosynthesis may occur during day and night.
STAGES OF PHOTOSYNTHESIS:
Photosynthesis is a metabolic reaction undergone by green plants to obtain their food using energy from sunlight. Photosynthesis is a process that involves two major stages: light independent reactions and light reactions. Light dependent reactions occur strictly under light conditions because light is needed to break down water molecules in a process called photolysis. In the light dependent reactions, water is broken down by light to give oxygen gas. In the light independent reactions, carbon dioxide is required.However, light independent reactions may occur during day and night. This is because light independent reactions does not require light to occur.

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.

1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

Dos condiciones anormales en el hombre, que son las cataratas y la fragilidad de huesos son debidas a alelos dominantes. Un hombre con cataratas y huesos normales cuyo padre tenía ojos normales, se casó con una mujer sin cataratas pero con huesos frágiles, cuyo padre tenía huesos normales. Calcula la probabilidad de: a) Tener un hijo completamente normal b) Que tenga cataratas y huesos normales c) Que tenga ojos normales y huesos frágiles d) Que padezca ambas enfermedades.
Answer:
La probabilidad de:
a) Tener un hijo completamente normal, cchh = 25%
b) Que tenga cataratas y huesos normales C-hh = 25%
c) Que tenga ojos normales y huesos frágiles ccH- = 25%
d) Que padezca ambas enfermedades C-H- = 25%.
Explanation:
Datos disponibles:
Alelo dominante C expresa cataratasAlelo recesivo c expresa visión normalAlelo dominante H expresa fragilidad de huesosAlelo recesivo h expresa huesos normalesLos posibles genotipos para cada característica entonces son:
CC y Cc ----> Cataratascc -------------> Ojos normalesHH y Hh ----> Huesos frágileshh--------------> Huesos normalesSabiendo esto, podemos deducir los genotipos del hombre y la mujer involucrados en la cruza.
Hombre con cataratas y huesos normales, tiene genotipo C-hhPadre del hombre tiene ojos normales, ccEl padre del hombre es homocigota recesivo, expresando ojos normales. Esto significa que solo pudo heredarle al hijo (el hombre) un alelo recesivo, c. Pero el hombre expresa cataratas, lo que significa que porta también un alelo dominante, probablemente heredado de la madre. Entonces el hombre es heterocigota para el tipo de ojos. Y puesto que tiene huesos normales, sabemos que es homocigota recesivo para esta característica.
Genotipo del Hombre: Cchh
Mujer sin cataratas y huesos frágiles, tiene genotipo ccH-Padre de la mujer con huesos normales, hhEl padre de la mujer tiene huesos normales, implicando que su genotipo es homocigota recesivo y que solo puede heredarle a la progenie alelos recesivos. La mujer tiene huesos frágiles, lo que supone que heredó el alelo dominante de su madre. Puesto que recibió un alelo dominante de la madre y uno recesivo del padre, la mujer es entonces heterocigota para la característica en cuestión. Ella también tiene visión normal, lo que significa que su genotipo para esta característica es homocigota recesivo.
Genotipo de la mujer: ccHh
Sabiendo los genotipos de ambos integrantes de la pareja, podemos realizar la cruza:
Cruza: Hombre x Mujer
Parentales) Cchh x ccHh

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.
