Meiosis is, a process in cell division. In this process the number of chromosomes decreases to half the original number. It occurs by two divisions of the nucleus and results in the production of 4 gametes.
Answer:
In meiosis I, one chromosome from each homologous pair goes to each daughter cell formed. ( In meiosis II the chromosome separates into two parts. One part goes into each daughter cell.)
Where dose mass of a willow tree come from
Answer:
So where does the mass come from? The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Which is NOT a function of the stem in plants?
O Store water
O Carry nutrients
O Provide support to the plant
O Anchor the plant in the ground
Answer:
yes D is the answer
Explanation:
cuz steam store water carry nutrients and of course provide support to the plant
Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.
What are stems?Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.
The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.
The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.
Therefore, option D. anchor to the ground is not provided by the stem.

The digestive and respiratory rely on the ___ system to
transport needed materials to the cells.
Answer:
Circulatory System
Explanation:
The digestive and respiratory rely on the circulatory system to transport needed materials to the cells.
What is circulatory system?The major job of the circulatory system is to transport oxygen, nutrients, and hormones throughout the body to the muscles, tissues, and organs. The removal of waste from cells and organs so that your body can get rid of it is another function of the circulatory system.
Through a system of arteries and veins, the heart circulates blood throughout your body (blood vessels). cardiovascular system is another name for your circulatory system. Vascular refers to blood vessels, while cardio is the word for the heart.
Blood devoid of oxygen travels along this circuit. Oxygenated blood is returned to the heart by the pulmonary veins.
Therefore, The digestive and respiratory rely on the circulatory system to transport needed materials to the cells.

importance of light and chlorophyll
Answer:
importancia de la luz y la cloro fila
Answer:
Light and chlorophyll are necessary for plants to photosynthesise. Photosynthesis is when plants use sunlight and carbon dioxide to make glucose. But chlorophyll is required to make this happen. It's important that plants make their own food so they don't die, since plants are the number one source of oxygen.
What receives nerve impulses?
A. Cell body
B. Dendrites
C. Axon
D. Myelin sheath
Explanation:
Dendrites receive nerve impulses from other cells.
Hope it help..The right answer is B. Dendrites receive nerve impulses.
What are Dendrites ?Dendrites are specialized structures on neurons that receive signals, or impulses, from other neurons or from sensory receptors in the environment. These signals can be either electrical or chemical, and they are transmitted across synapses, which are tiny gaps between neurons or between neurons and effector cells, such as muscles or glands.
Dendrites play a crucial role in the transmission and processing of these signals. They are covered in tiny protrusions called dendritic spines, which increase the surface area of the dendrite and allow for a greater number of synapses to be formed with other neurons. This increased connectivity enables the dendrite to receive and integrate signals from multiple sources and to process them in a highly sophisticated way.
Once the signals are received, they are transmitted to the cell body of the neuron, where they are integrated and processed before being transmitted along the axon of the neuron. The axon is a long, slender extension of the neuron that carries the electrical impulses from the cell body to the axon terminals, which are specialized structures that form synapses with other neurons or with effector cells.
In summary, dendrites are specialized structures on neurons that receive signals from other neurons or sensory receptors, and they play a key role in integrating and processing these signals before transmitting them to the cell body of the neuron. This allows the neuron to perform complex computations and respond to the environment in a highly sophisticated way.

_______________ and ________________________________ factors can affect an organism’s traits.
Answer: Genetic makeup and environment
Explanation:
Genetic makeup of an organism is dependent upon the genes inherited from the parents. The genes when express are responsible for the development of specific traits in an organism. The environment is also responsible for contributing to the development of traits in an organism. For example, an organism is able to tolerate the cold environmental conditions and can survive in cold habitat as it has inherited traits from the parents but when exposed to hot environmental conditions then it will adapt to the changes in the environment due to development of heat tolerant trait. Also a person has inherited traits of short height from parents but when provided with nutritious food and performs regular physical activities the person had attained tallness due to environmental factors.

I got to compare a plant and animal cell! the plant cells are similar to brick walls. nice and organized! while animal cells were... messy. I wonder what other things would look like under a microscope, like bacteria, or I wonder how long it would take to watch a cell go through the cell cycle under a microscope!

1. A common misconception is that plants perform photosynthesis INSTEAD of cellular
respiration. This is incorrect because plants carry out BOTH photosynthesis AND
Cellular respiration
Explain why plants need to use both process in order to survive,
Answer:
Please find the explanation below
Explanation:
Photosynthesis is the process whereby plant cells manufacture their energy source or food (glucose) in the presence of sunlight. Cellular respiration, on the other hand, is the process by which living cells release energy in form of ATP needed by their cells for cellular activities.
Living organisms eat or obtain take in food in order to obtain energy for their cellular upkeep. Plants are one of the only set of organisms that can produce their own food i.e. autotrophic and they do so via PHOTOSYNTHESIS. However, they need to undergo cellular respiration in order to breakdown the synthesized food to yield usable energy for their cells. These two processes in plants are direct metabolic opposite of one another.
Based on the explanation above, plants need to use both PHOTOSYNTHESIS AND CELLULAR RESPIRATION because the products of one yields reactant for the other. photosynthesis uses carbon dioxide released by cellular respiration while cellular respiration uses oxygen released by photosynthesis.

Answer:
A i think lol
During replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.
What is replication of DNA?Replication of DNA is defined as the biological process of splitting a single DNA molecule into two identical copies. A double-stranded DNA molecule is copied to create two identical DNA molecules during the DNA replication process. The three primary stages of replication are priming of the template strand, building of the new DNA segment, and opening of the double helix and separation of the DNA strands.
All biological cells contain it, and even though its synthesis takes place in the nucleus, it typically occurs in the cytoplasm of the cell. While DNA provides the instructions for the actions of the cell, RNA is in charge of translating those instructions into proteins that perform diverse cellular tasks.
Thus, during replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.
