The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal. Credits: internet source

1.True or false: It may be possible to save a significant proportion of Earth's biological diversity by establishing sustainable

1. True. Establishing more sites for the protection of biodiversity across the world can go a long way and would have a chain reaction in the ecosystem. Thus, it will save a lot of our planet's biodiversity. 2. a. -Philiab. -trophicc. eco-d. eu-3. A habitat is where certain species, animals, or organisms naturally live, feed, reproduce, etc. Examples: ocean, rainforest, deserts. An ecosystem has two components: living and non-living organisms which interact with each other to maintain homeostasis. The primary difference between the two is the presence of interaction between the things in the environment.4. Energy5. Producers6. Sun7. (No choices provided) One of the top factors that threaten the survival of species is caused by humans, man-made phenomena. 8. Answer: Polar bears. Polar bears are endangered species and there are only approximately 20,000-30,000 polar bears left in the world. Their population had been decreasing due to habitat loss because of climate change. 9. Scientists based the background extinction rate on the number of known species that went extinct over a period of time in the past. They also based it on archaeological evidence of species that existed and went extinct years ago.

After crossing over as shown below what would the sequence of genes be for each of the chromatids

SashulF [63]

The sequence of the genes will be ABCD, abCD and abCd, abcD.

Full question is attatched below.

<h3><u>Explanation:</u></h3>

The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.

Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.

Here the d gene of the two chromosomes are getting exchanged.

So the chromosomes will become ABCD, abCD and abCd, abcD respectively.
