Answer:
The correct answer is - chromosomes.
Explanation:
Walther Flemming is a german scientist who named mitosis for the first time in the year 1882. Mitosis is the process of cell division in which a parent somatic cell into two daughter cells after the nucleus splits in two.
The word "mitosis" means "threads," or strands in the greek word mitos which refers to the thread-like or string-like appearance of the chromosomes during interphase and early prophase.
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.

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.

How are the biomolecules used to fuel the body and maintain homeostasis?
Explanation:
The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
Answer:
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
Viscosity refers to the thickness of blood. This thickness is caused by the number of red blood cells. Thick blood travels through blood vessels at a slower rate than thin blood.

What can engineers do to protect ecosystems from invasive species ?
will mark brainliest !!!!
Answer:
By extensively filtering the water in a lake or a bay they can clear it enough to increase light penetration thus affecting benthic macroalgal communities by facilitating growth. There are numerous examples of animals and plants that function as ecosystem engineers.
In ecosystems engineers by altering their receptive environment, invading species have the potential to play a dominant role as ecosystem engineers and can have an ecosystem-level impact by hindering or facilitating other species, whether invasive or native.
What are ecosystems engineers?Ecosystem engineers are organisms that alter the physical condition of biotic or abiotic materials to affect the availability of resources (other than their own) to other species. By doing this, they alter, preserve, or even create new environments.
They can clear the water in a lake or bay sufficiently to promote light penetration, which will influence benthic macroalgal ecosystems by promoting growth.
Therefore, there are many instances of plants and animals that act as ecosystem engineers.

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.

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.
