Answer:

The cells belong to the tissue level of organization

Explanation:

Living organisms are composed of four levels of organization; the cell, tissues, organs and organ systems.

The cell is the basic unit of life and the smallest level of organization.

Tissues are group of cells with a common origin which work together to perform a similar function.

Organs are composed of different types of tissues and perform various complex functions. in the organism.

Organ systems are groups of organs that perform similar functions or which work together for a specific function.

A plant leaf is an organ which is made up of various tissues such as the dermal, vascular and ground tissues.

The dermal cells known as the epidermis belong to the tissue level of organization as they perform a similar function of protecting against mechanical injury and invasion by microorganisms

A, B, C, D and E are pathogens of different diseases for human beings. The route of entry of pathogens in human body is differen

Goryan [66]

Answer:

Microorganisms which causes diseases is known as pathogen.

Explanation:

PATHOGEN -: Pathogens are agents that live in a host and are responsible for causing infections or diseases in that host, such as a human being. Microorganisms such as bacteria , viruses , fungi or protozoa, or other organisms such as parasites, worms and even contagious proteins such as prions, may be pathogens.

Viruses: Viruses are micro-organisms that are composed of nucleic acid and covered by a protein sheet. A lipid (fatty) outer layer is also present in some viruses. Enveloped viruses are called these. Non-enveloped viruses are considered those that do not have this lipid outer layer. Only inside their host's living cells are viruses able to replicate. EXAMPLE -: Influenza (influenza A and B viruses) and the common cold (rhinovirus) are examples of infections caused by viruses.

Bacteria: These are microorganisms which have a nucleus containing DNA surrounded by a cell wall or membrane. Among bacteria, the composition of the cell wall differs. If they are able to access food and nutrients, they have a more complex structure than viruses and can multiply beyond the host. EXAMPLE -: Foodborne diseases can be caused by bacteria such as Salmonella enterica and Escherichia coli, while Staphylococcus aureus can cause skin infections.

Fungi: Fungi are single-celled or multicelled species that can live outside a host. They consume food and nutrients created after digestive enzymes have been secreted into their atmosphere. example-:  The foot of the athlete (Trichophyton mentagrophytes) and yeast infections (Candida albicans) are examples of infections caused by fungi.

Prions: These are infectious agents made up entirely of proteins and capable of transferring to other prion proteins their infectious properties. EXAMPLE -: Extreme infectious diseases such as bovine spongiform encephalopathy (mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) can be caused by prions.

Protozoa: Protozoa are single-celled organisms that display habits that are similar to animals, such as the ability to travel through water, and are capable of harvesting other microorganisms. They are able to live outside the human host, but when they enter the human host and spread, causing infections and diseases, they may also be parasitic in nature.  EXAMPLE -: Malaria and giardia include common infections

Yes , pathogen enter into the body directly -: Direct contact infections spread when, through direct physical contact with blood or body fluids, disease-causing microorganisms move from the infected person to the healthy person. Touching, kissing, sexual contact, contact with oral secretions, or contact with bodily lesions are examples of direct contact.
INCUBATION PERIOD OF A PATHOGEN -:The period of incubation is the interval between exposure to a pathogenic organism, a drug, or radiation, and when the first signs and symptoms are evident.

Which statement best describes the orbit of Earth?

ruslelena [56]

Answer:

B. Earth rotates on its own axis and revolves around the Sun.

Explanation:

The earth moves not only in one way but in two ways. It revolves around its axis and revolves around the Sun.

We do not notice it because we are on Earth and we turn together with it.

When the Earth revolves around its (imagined) axis, we call such a movement a rotation, and when it revolves around the Sun - a revolution.

WARRIOR [948]

Answer;

Chlorophyll

Chlorophyll is the green pigment found in plants traps energy from the sun for photosynthesis.

Explanation;

-Green plants requires food for their day to day activities, thus they use the process of photosynthesis to make their own food, which they use to generate energy or store for the future use in form of starch.

-Chlorophyll a pigment that gives plants their green color is vital during the process of photosynthesis. During the first phase of photosynthesis light dependent stage), chlorophyll traps sunlight which is used to split up water molecules to oxygen atoms and hydrogen ions, a process called photolysis.
