Answer:100% SURE PLZZ GIVE BRAINLIEST!!!!!!111

The nervous system consists of two major parts: the central nervous system and the peripheral nervous system.

Explanation:

In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.

9. A food scientist baked one cookie dough sample at 350 degrees F for 13
Anna71 [15]

Answer:

There is no control.

Explanation:

If the scientist was testing something based on the different temperatures, they would need the amount of time in the oven to be the same for each cookie so that they can compare them. Without the times being the same, the scientist would not be able to tell whether the temperature or the time in the oven caused the differences in the cookies.

The color of a star is primarily determined by its _____. composition size apparent brightness age surface temperature
VLD [36.1K]
The color of a star is primarily determined by its surface temperature.

For example, the really hot stars, called White Dwarf stars, have a white surface temperature, while a cooler star would have a more red color.

What are the steps of the Lytic cycle?

Certain viruses have a cloaking cover made of a protein-lipid combination with glycoprotein projections from the surface. These viruses, such as mumps, use their glycoprotein spikes to simulate a normal protein and thereby mask their identity so they can attach to receptor sites on the cell membrane of the host.  

 

 

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes.Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.  

 

Characteristics of Eubacteria - Real Bacteria.Bacteria are all known as prokaryotes. Prokaryotes are organisms that lack a cell nucleus and other cellparts, and tend to be less complex. Eubacteria/bacteria also possess cell walls made of peptidoglycan, a chemical that gives their cell wall added strength  

 

Essential bacteria. ... Some bacteria degrade organic compounds for energy, and without bacteria, the earth would have no soil in which to grow plants. Bacterialiving in the gut can help animals break down food. These so-called 'good bacteria' help maintain the conditions necessary for food digestion.  

 

Disease-causing bacteria can cause illness. Viruses can also cause illness. ... Because of this widespread use, the infectious bacteria the antibiotics were designed target have adapted and changed, making the drugs less effective  

 

There are several archaebacteria kingdom characteristics that help in distinguishing them from eubacteria. These characteristics of archaebacteria are as follows: Archaebacteria have no peptidoglycan in their cell walls. The cell wall is made up of glycoproteins and polysaccharides.  

 

Plant cells, and some protists have chloroplasts, though animal and fungal cells lack them. Prokaryotes do not have chloroplasts (or any other organelles), though some can carry out photosynthesis, its cell acting like one bigchloroplast. In most cases, chloroplasts are green  

 

General Characteristics of Fungi:  

Eukaryotic.  

Decomposers – the best recyclers around.  

No chlorophyll – non photosynthetic.  

Most multicellular (hyphae) – some unicellular (yeast)  

Non-motile.  

Cell walls made of chitin (kite-in) instead of cellulose like that of a plant.  

Are more related to animals than plant kingdom.  

 

 

Plants have chlorophyll, a green pigment necessary for photosynthesis;  

Their cell walls are made sturdy by a material called cellulose; and.  

They are fixed in one place (they don't move).  

 

Xylem is the vascular tissue responsible for the transport of water and nutrients from the roots in the soil to the above-ground parts of the plant. Hormones and other small molecules also travel through the xylem as they are moved throughout the plant.  

 

Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant viaphloem.  

 

The main difference between vascular and nonvascular plants is that avascular plant has vascular vessels to carry water and food to all the different parts of the plant. The phloem is the vessel that transports food and the xylem is the vessel that transports water.  

 

The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. ... The organ systems of a typical plant are illustrated below. The shoot system of a plant consists ofleaves, stems, flowers, and fruits. The root systemanchors the plant while absorbing water and minerals from the soil
