Answer:

Explanation:

1:

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

2.

The basic plant cell has a similar construction to the animal cell, but does not ... It does have additional structures, a rigid cell wall, central vacuole, ... namely xylem, which is involved in structural support and water conduction, ... to provide energy, particularly when light isn't available for the chloroplasts to produce energy.

3.

What structures does a plant cell have that an animal cell does not have? ... The centrosome is a region near the nucleus of animal cells that functions as a ... Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. ... Like mitochondria, chloroplasts also have their own DNA and ribosomes.

4. Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant ... Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for ... Like mitochondria, chloroplasts also have their own DNA and ribosomes. ... The central vacuole also functions to store proteins in developing seed cells.

5. Animals cannot use radiant (light) energy in this way. They must ... What change had the plant made to ... However, Earth's atmosphere has not always contained oxygen gas. During ... form of glucose or they eat other animals that ate plants.

Answer:

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Explanation:

Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.

Suppose the rate of plant growth on isle royale supports an equilibrium moose population of 850 moose in this scenario there are
lesya692 [45]

The population of moose will still be around 850 in 30 years.

<h3>What is carring capacity?</h3>

Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.

With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.

So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.

A fossil is found to have a 14c level of 67.0% compared to living organisms. how old is the fossil?
sp2606 [1]
The half-life  of carbon-14 is equal to 5730 years. The amount of substance with half-life h at any time t is equal to,
                       At = (Ao) x (1 - 0.5)^(t/h)
Substituting, 
                    At/Ao = 0.67 = 0.5^(t/5730)
The value of t from the equation is 3310.6 years.

What are the subunits called that make up carbohydrates?
neonofarm [45]

Answer:

Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have <u>carbon</u>, <u>hydrogen</u>, and <u>oxygen</u> in a 1:2:1 ratio.

Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.

Make an example...

Short carbohydrate chains are called <u>oligosaccharides</u> and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of <u>glucose</u> and one molecule of <u>fructose</u> joined together.
