never [62]3 years ago
3 0

Answer:

.02

Explanation:

When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.

I may not be able to make you a presentation, but I can help you on the idea behind it. Photosynthesis is 6 Carbon dioxide 6 water and light to make glucose and oxygen. With cellular respiration, its the opposite. Glucose + oxygen to break it down and forms waste products of 6 carbon dioxide and 6 water. The main thing it produces though is ATP (Adenosine Triphosphate). ATP is the product of cellular respiration and is fuel for your cells to function. I hope this helps. There are different stages in photosynthesis and cellular respiration that I’m not going to dive into, but this is the main reason why they depend on each other. Because unlike humans where we eat food, they use photosynthesis to make their glucose which they turn into ATP energy. Think I covered most of it. Good luck on your presentation!

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I
Bogdan [553]

Answer:

<u>Sister chromatids are identical  forms of chromatids  of a chromosomes. They are mostly  formed by semi-conservative replication of DNA molecule of a single  chromosome.Thus they  are  like  </u><u>'photocopies' </u><u> of  original parent  chromosomes; joined together at the Centromere</u>.

They are exactly similar in all ramification; with the same gene and allele compositions..

<u>However; slight differences  arise between the two identical sisters due to  </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in  the  length of telomere repeats.</u>

Non-sister chromatids are dissimilar forms of  chromatids of a chromosomes formed  when each half of  a chromosome  at fertilisation from separate   haploid sex-cells, of each parent. fused.They contain different genetic composition;because  they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

<u>However, they are genetically  similar in composition; if they  are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by  chromosomal crossing-over between the non-sister chromatids  on the chromosomes ; therefore identical genetic characteristics are shared .

Help, I don't get this
Evgen [1.6K]

Answer:

Letter A represents the greatest potential energy.

Letter C represents the least potential energy.

Letter C represents the greatest kinetic energy.

Letter A represents the least kinetic energy.

Letters A and C represent an equal amount of both potential and kinetic energy.

Explanation:

Potential energy is a put away energy that relies on the overall situation of different pieces of a framework. A spring has progressively potential energy when it is packed or extended. A steel ball has more potential energy raised over the ground than it has in the wake of tumbling to the Earth. In the raised position it can do more work. Potential energy is a property of a framework and not of an individual body or molecule; the framework made out of the Earth and the raised ball, for instance, has progressively potential energy as the two are more distant isolated.\

Kinetic energy is a type of energy that an article or a molecule has by reason of its movement. In the event that work, which moves energy, is done on an item by applying a net power, the article accelerates and along these lines increases kinetic energy. Kinetic energy is a property of a moving item or molecule and depends on its movement as well as on its mass. The sort of movement might be interpretation (or movement along a way starting with one spot then onto the next), turn about a pivot, vibration, or any blend of movements.
