Answer:
C Es el tejido formado por fibras musculares que tiene movimiento involuntario y forma órganos internos
Explanation:
El tejido muscular es un tipo de tejido formado por células contráctiles especializadas llamadas miocitos. El tejido muscular se divide en tres clases diferentes: tejido muscular esquelético, tejido muscular cardíaco y tejido muscular liso. El tejido muscular esquelético es aquel que se mueve de acuerdo a la voluntad del individuo, cuyas células son multinucleadas y poseen una gran cantidad de mitocondrias. El tejido del músculo cardiaco es involuntario y está formado por células uninucleadas (miocardiocitos) las cuales componen las paredes del corazón. Finalmente, el tejido muscular liso también es involuntario y está formado por células uninucleadas con el núcleo en el centro. Las células musculares lisas contienen un citoplasma con haces de filamentos de actina y miosina los cuales están organizados más irregularmente que en fibras musculares estriadas. Este tipo de tejido (músculo liso) se localiza en las paredes de los órganos internos o víseras como, por ejemplo, el tracto gastrointestinal, conductos de glándulas, el sistema urinario, etc., y en los vasos sanguíneos.

Which of the following statements about DNA (deoxyribonucleic acid) is NOT true?
Answer:
D
Explanation:
When a trait is always expressed, it is considered to be a
trait.
O Recessive
O Codominant
O Dominant
O Incomplete
Answer:
O Dominant
Explanation:
An allele that is always expressed whenever it is present is called dominant. Mendel's law of segregation states that the two alleles for a trait segregate independently when gametes are formed.
Hope this helped!!!!!
A dominant trait is a form of trait which is ALWAYS expressed.
Subject is Science: I need help plzzz!! If we have two different layers of water, one has a temperature of 70 degrees and one has a temperature of 30 degrees, which layer is going to be at the bottom? 30 degrees or 70 degrees?
Answer:
70 degrees water will be at the bottom. Ice floats, so it would make sense for the colder water to rise. Sorry if I'm wrong :>
What are examples of things that can cause mutations?
Answer:
Exposure to chemicals.
Explanation:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

Answer:
The cell’s membrane separates the cytoplasm, forming two cells.
Explanation:
Cytokinesis is the physical process during cell division that separates the cytoplasm of the parental cell into two different daughter cells. Cytokinesis occurs after the telophase of mitosis. During this process, the cell membrane grows to surround each daughter cell and thus separate them. In animal cells, cytokinesis occurs by a ring of contractile microfilaments that lead to the constriction of the parental cell.

The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. hormones plasma protein electrolytes glucose
Answer:
plasma protein.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.
Plasma comprises of about 97 percent of water by volume and it typically contains mineral ions, glucose, carbon dioxide, hormones, plasma protein, etc.
Hence, the fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of plasma protein.

Explanation:
Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.
TIMED!!! WILL MARK BRAINLIEST! 40 POINTS!!! Explain how a forester can make sure that an area is harvested sustainably.
Answer:
Foresters are responsible for determining areas that can be harvested sustainably and helps monitor areas to be harvested. Foresters determine which areas have trees that can be removed without causing harm to the environment and ensures that areas are not overharvested.
What effect did an increasing human population have on the sustainability of a managed ebony forest?
A) The ebony forest population increased when managed, even as the human population grew. As the human population grew, forest management caused more trees to be produced.
B) The ebony forest population remained stable when managed, even as the human population grew. Forest management allowed more trees to be grown.
C) The ebony forest went extinct. As the human population grew, it was not possible to maintain the forest, even when it was managed.
Answer:
B
Explanation:

Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities. Which of the following processes contributes to the transfer of carbon to the atmosphere?
A.
photosynthesis
B.
formation of fossil fuels
C.
precipitation
D.
volcanic eruptions
The processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.
What is carbon cycle?The cycle in which transfer of carbon to the atmosphere from the Earth and back into the atmosphere is called carbon cycle.
Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities.
Let's check all the options one by one-
A. Photosynthesis- This is a process through which the plants transfer light energy into chemical energy. In this process, carbon move from atmosphere to the biosphere.B. Formation of fossil fuels-The fossil fuels are developed by decomposing plants and animals in a million of years. This decomposition contributes to the transfer of carbon to the atmosphere.C.Precipitation- Precipitation is the product of water cycle, which falls by gravitational pull from clouds.D. Volcanic eruptions-The product such as lava and the gases which are released by a volcano is called the volcanic eruptions. These eruptions add carbon to the atmosphere.Hence, the processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.

Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
