Cells must move materials through the {membrane} and throughout the {cytoplasm} to maintain {homeostasis} Movement of substances is regulated because membranes are {semi} permeable. Membranes are {phospholipid} bilayers that contain embedded {proteins} The cells external environment and cytoplasm are aqueous, meaning that solutes such as {salt}are dissolved in a solvent called {water} Water may travel slowly through the membrane by {osmosis} or quickly through protein channels called {aquaporins}
Answer:
Testes are the structure in male organism where sperm cells are produced. The process in which sperm cells are produced called spermatogenesis. Ovaries are the structure in female organism where egg cells are produced. The process in which egg cells are formed is called oogenesis.
When sperm of male combine with egg of female, it produces a fertile zygote and this zygote turns into a new organism.
The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.
Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.
Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
Answer:
The answer to the enunciated: your employer lets you know that the safety data sheets are located on a computer in his office. Does this comply with employer responsibilities? is:- This act doesn't comply with the responsibilities of the employer.
Explanation:
The responsibilities of the employer are to guide the employed about the things in the company, of the sentence you can deduct two sceneries:
- The employed is in training in the company, the reason why the employer is saying to him where are the safety data sheets, but the correct would be to show the sheets and how function them.
- The safety data sheets are reserved for people with a high rank in the company, the reason why the employer must not say it to the employed.
Answer:
The value of the expression is as follows:
a = 10; B = 2.5; c = 7
Explanation:
a = 4B = 3 + c = 10
Step 1
split equation into parts, then we have
3 + c = 10
c = 10 - 3
c = 7 (the value of c is 7)
Step 2
Rewrite equation as a = 4B = 10, then split again
4B = 10
Then, B = 10➗ 4
B = 2.5 ( the value of B is 2.5)
Step 3
Take the last part of the equation
a = 10 (the value of a is 10)
Note the "equal sign =" put whatever is on the left hand side to be equal to the right hand side
