Blood cells are membrane-bound, circular, biconcave discs that have no nuclei at maturity.
What are blood cells?Blood cells are round, disc shaped cells, that constitute the blood.
There are three types of blood cells:
White blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages) Red blood cells (erythrocytes)Platelets.The red blood cells help to carry oxygen to the body.
White blood cells help in immunity of the body.
The platelets involve in the process of hemostasis.

What two forms of energy are produced by nuclear fusion?
Answer:
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.

true or false? mitosis takes place during m phase, which is the longest phase of the cell cycle.
Answer:
False
Explanation:
Mitosis takes place during M phase of the cell cycle, which is longer than interphase. False. Although mitosis takes place in M phase, M phase is shorter than interphase; cells spend most of their time in interphase.
why does cell division occur in sexually reproducing organisms?
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.

Why is it bad when extra nitrogen leaves the soil?
Answer:
When plants lack nitrogen, they become yellowed, with stunted growth, and produce smaller fruits and flowers. Not enough nitrogen in the soils leaves plants hungry
Explain in your own words the difference between a leading strand and a lagging strand.
Answer:
So basically the primary distinction between the leading and lagging strands is that the leading strand is the DNA strand that develops continuously during DNA replication, whereas the lagging strand is the DNA strand that grows in small pieces known as Okazaki fragments. A leading strand is one that is produced in the 5'-3' direction, whereas a lagging strand is one that is formed in the 3'-5' direction. The leading strand is constantly produced where the other is not.

1. Which layer is found at Earth's center?
mesosphere
mantle
crust
core
Answer:
The Core
Explanation:
The very center of the earth is called the core.
The core layer is located at the center of the Earth.
What is center of earth?All land surfaces on Earth have a geometric center that is located at the planet's geographic center. According to geometry, it is the centroid of all land areas inside the two dimensions of the geoid surface, which roughly represents the exterior shape of the planet.The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core. The Earth's core is around 2,900 kilometres (1,802 miles) below the surface and has a radius of about 3,485 kilometres.Since the temperature and pressure significantly rise as we travel more inside the planet, we are unable to reach the center of it. Furthermore, there is currently no technology that can penetrate the depths of the earth.To learn more about center of earth refer to:

Suggest how the scent from the flowers
spreads out into the air
Answer:
through diffusion
Explanation:
I think so that by diffusion this occurs
Answer:
Pollinators which may be insects, birds, or other animals would reach the flower by being stimulated through their sense of smell. The scent from flowers gets spread through the air everywhere because the scent producing molecules are low weight. The low molecular weight help them spread and diffuse everywhere

A) Mitochondria.
B) Nuclei.
C) Ribosomes.
D) Vacuoles
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the MITOCHONDRIA. These organelles (mitochondria) are the energy centres of the cell.
Cellular respiration is a series of metabolic reactions by which the cell produces energy in the form of ATP by using the energy stored in the chemical bond of simple carbohydrates and oxygen.
Cellular respiration has three stages: glycolysis, the citric cycle and oxidative phosphorylation.
Glycolysis occurs in the cytoplasm, whereas the citric cycle and oxidative phosphorylation take place in the mitochondria.

Most of the iron that is removed from degraded hemoglobin is: recycled to the red bone marrow.
Most of the iron removed from degraded hemoglobin is recycled in the red bone marrow.
What is Hemoglobin?Hemoglobin is defined as an iron-containing oxygen-transporting metalloprotein present in the red blood cells of nearly all vertebrates as well as the tissues of some invertebrates that carries oxygen from the respiratory organs in the blood to the rest of the body.
The blood protein hemoglobin that helps carry oxygen throughout the body and carbon dioxide to your lungs. High hemoglobin levels can cause dizziness, fatigue, easy bruising, and other symptoms.
The iron which is present in hemoglobin which is removed is recycled from the red bone marrow.

What happens during the light-dependent and light independent reactions of photosynthesis?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
The energy from sunshine is collected by chlorophyll and transformed into stored chemical energy through light-dependent processes. Chemical energy is used in light-independent processes.
The stroma is where photosynthesis' light-independent processes take occur. It includes enzymes that, in conjunction with ATP and NADPH, “fix” carbon from CO2 into molecules that may be utilised to make glucose. The stroma also stores the chloroplast's own genetic material (which is distinct from that of the cell).
the lysis of red blood cells in blood agar is indicative of the presence of which enzymes?
cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
Explanation: One cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
BAP assesses an organism's ability to produce hemolysins, enzymes that damage/lyse red blood cells (erythrocytes). The degree of hemolysis caused by these hemolysins aids in the identification of members of the genera Staphylococcus, Streptococcus, and Enterococcus.
What hemolytic pattern does S aureus shows on BAP?On blood agar plates, colonies of Staphylococcus aureus are often encircled by zones of clear beta-hemolysis. The golden appearance of colonies of some strains is the etymological root of the bacteria's name; aureus meaning "golden" in Latin.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, causes hemolysis. Intense physical activity is another cause. Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, is one cause of hemolysis. Intense physical activity is another cause.
