Can carbon move from a living component of an ecosystem to a nonliving component

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo

Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA RNA

A-T A-U

T-A T-A

C-G G-C

G-C C-G

Given the sequence the transcription will be as follows:

DNA : TGG - AAC - CAA

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time). Let's take the first codon in your sequence:

ACC

1st 2nd 3rd

A C C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.

Biodiversity

rodikova [14]

Answer:

Please find the complete paragraph below; the missing words are inputed in bold.

Explanation:

One of the most important bioethical issues facing us today is the issue of _____EXTINCTION____or a loss of biodiversity

2. Defined as variation of life on Earth __BIODIVERSITY___is the number and relative abundance of different __SPECIES__.

3. It is estimated that there are as many as __8.7 million__ species in the world though as few as __2.3 million_have actually been identified.

4. As the human population grows and demands more resources, ___BIODIVERSITY_ is threatened.

5. Human activities contribute to habitat loss, especially in the world's coral reefs and tropical rain forests. As a result, some organisms face __EXTINCTION_or the death of their species

6. The growth of the __HUMAN___ population has destroyed up to 25% of _BIODIVERSITY__ and threatened another 30% statistics are similar for __ECOSYSTEM___ .

7. Humans also face __NEGATIVE___ consequences in that we are dependent on the ecosystem we are destroying for everything from food to raw material.

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic

rjkz [21]

Answer:

Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

 Animal Cells Vegetable Cells

Cell wall NO YES

Vacuoles YES, Small and more than ones YES, Only one and big

Chloroplast NO YES

Plasmatic membrane YES YES

Mitochondria YES YES

Lysosomes YES YES

Endoplasmic reticulum YES YES

Golgi apparatus YES YES

Cytoplasm YES YES

Ribosome YES YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

Cell wall: A rigid structure that provides support and protection.

Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

Chloroplast: these are organelles that accumulate chlorophyll.

Animal cells do not have chloroplasts because they do not photosynthesize.
Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

Vacuoles:

Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
