Answer: hypothesized that the higher pH levels would increase the rate

of movement of the Artemia. The students placed the Artemia in petri dishes with 2 mm x 2

mm grids marked off on the bottom of the dishes. The students calculated how fast the Artemia

traveled in each pH (4-9) solution by counting the number of squares on the grid that the

Artemia crossed per second of timing.

The data collected from their experiment is presented below:

pH of Water

Rate of Movement of

Artemia

(squares per second)

1. Using the grid below, create a graph based on the above data.

Explanation: yes

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would

Aleksandr [31]

Answer:

Three different kinds of muscles are -:

SKELETAL MUSCELES
CARDIAC MUSCLES
SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.
CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart.
SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.

Explain the process of cellular respiration. list the raw materials and products of this process. tell how the body eliminates t

sladkih [1.3K]

Hm, raw materials: three stages exist in the electron transport: It is, glycolysis, citric acid cycle, and electron transport.

In animals, like humans, waste products of aerobic respiration is, water and carbon dioxide, and waste product of anaerobic respiration are lacic acid.

Hope this helps alot!! -Aparri

Which of the followinf is a reason the residents of montevideo be glad about the reopening of wl observatorio meterorologico del

cestrela7 [59]

Answer:

Meteorological observatory of the Pio College (observatorio meterorologico del colegio pio) was started in the 7 May 1982. This network station mainly covers the area of 30th degree of southern latitude with the tips of Atlantic ocean.

The montevideo residents are glad about its reopening because this station has the ability to recognize the dangerous storms. The early warning signs are generated about the storms that might affect the near by area of the locality.
