The possible four base long sticky end will be AATT or TTAA.

Option C.

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

The restriction endonuclease enzymes are those enzymes which can cut a portion of DNA at specific base pair sequences. This restriction endonucleases sometime cuts the DNA in such a manner that often some of the nucleotides become pairless and remain as lone nucleotides, which are called as sticky ends.

Here, the said restriction endonuclease cuts the DNA at the sequence GTTAAC. If the DNA has a sticky end with 4 sticky nucleotides, then the possible cuts are at the portions G / TTAAC and at C/ AATTG. Here the portion TTAA or the portion AATT remains pairless in the cut portion which is the four nucleotide long sticky base.

stiks02 [169]
The organelle in the plant that will most likely store the absorbed herbicide waste is the vacuole. Vacuoles act as storage bubbles in plant cells. They could store various materials such as food or nutrients to help the plant survive. It can also store waste materials to prevent them from contaminating the entire cell.

An imaginary species of bears, fur color can be purple or gold. Gold is the dominant trait. How would the bear look if the gene
BARSIC [14]

Answer:

<h2>Gold</h2>

Explanation:

Assume Gold trait =P ,

Purple= p,

Given:

Gold (P) is dominant over purple(p), so P is dominant over p.

If the bear is homozygous pp ( recessive)  then bear will look purple,

If the bear is heterozygous Pp, then bear will look gold,

If the bear is homozygous DD( dominant), then the bear will look GOLD,

Explain any two specific adaptation that allow animal to survive in Mountain habitat<br><br>​
IRISSAK [1]

Answer:

Among others, two adaptations might be

  1. Avoiding corporal heat loss
  2. Increasing oxygen absorption  

Explanation:

Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:

  • Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
  • Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
  • Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
  • Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
