Lysosomes ( common in animal cell but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion in white blood cells that eat bacteria) lysosomes contents are carefully released Into the cytoplasm can also cause cell death.  

Peroxisomes: this organelle is responsible for protecting the cell form its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria .The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.

Secretory vesicles: cell secretions –e.g, hormones, neurotransmitters, are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for releases.

Answer:

Lysosomes are spherical pouches that have digestive enzymes. It allows the digestion of bacteria, viruses or some toxins, they also allow the breakdown of glycogen and the release of thyroid hormone, they also break down the bone allowing the release of calcium.

While secretory lysosomes are located in white blood cells, in immune cells such as melanocytes.

On the other hand, peroxisomes are membranous sacs that are made up of oxidases and catalases. They are responsible for neutralizing free radicals and free radicals from highly reactive chemicals.

Carbohydrates are made from three elements known as Carbon, water, and oxygen.

DNA is made up of phosphate sugar groups for the helix and nitrogenous bases for the inside.l

Lipids also are only made form carbon, water, and oxygen but in a different ratio.

Why is it important to avoid applying too much nitrogen fertilizer?
solniwko [45]

Answer:

too much nitrogen in surface runoff can cause algae to overgrow

Nitrogen fertilizers used in large-scale agriculture could leave a legacy of pollution that would persist for decades in soil and groundwater, scientists in France and Canada warned, which published a study in the National Academy of Sciences magazine, " PNAS ". According to these scientists, the excess of these fertilizers in the environment has been linked to contaminated drinking water and can cause the rapid growth of algae that compromise aquatic ecosystems and coastal marine life.

Scientific study of the population cycles of the snowshoe hare and its predator, the lynx, has revealed that
ladessa [460]
This scientific study revealed that predation is the dominant factor affecting prey population on cycling. Population cycles is the feature where populations rise and fall over a predictable period of time. For example there are some species where population numbers have reasonably predictable patterns of change. From the study depicted in the question; when snowshoe hares are scarce, many lynx leave their home range in search of food. An increased predation of the hare due to high populations of lynx and other predators increases the decline in the hare population.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.
