An interesting observation made by the firefighters was that some parts of the forest seemed to escape the flames. The crown fir
Savatey [412]

Answer:

According to the previous observational study it is possible to notice that thinning determined in great way the rate of trees that survived the fire.

Explanation:

In general the trees that had been previously cut, were the ones that presented more resistance to the fire, while the trees that had not been thinned were the ones that were severely affected in the spreading conflagration. Reason why in comparison of these two samples, it would be possible to conclude that previously cutting down trees can survive better to the spreading fire.

Base your answer to the question on the information below and on your knowledge of biology.
vodomira [7]

Answer:

They can perform photosynthesis.

Explanation:

Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.

The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.

To keep the humeral head centered within the glenoidal cavity the rotator cuff muscles must be __________. Select to launch anim
enyata [817]

Answer:

<h2> located in the same plane</h2>

Explanation:

  • Such types of muscles and tendons that play an important role in the stabilization of the shoulder are called rotator cuff muscle.
  • These muscles are responsible for the different types of motion and simply called a different range of motion.
  • Muscles like scapulohumeral muscles,  infraspinatus muscle and some others are grouped as rotator muscle.
  • These muscles are involved in the movement of the shoulder and also stabilize the joints of the shoulder for the movement and during the movement.
  • When the humeral head is centered within the cavity of the glenoidal then the rotator cuff muscle should be on the same plane.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cel
Leviafan [203]

Answer:

large central vacuole

cell wall

Explanation:

Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.

Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
