The geneticists studying the alien organisms have deciphered their genetic code. For Familiarity, they have used A, C, G, and T to indicate the bases in this code. A comparable genetic sequence in each alien has been identified in the genes that code for eye growth. This genetic sequence has allowed the aliens to be divided into six groups, with the single-tail three-eye group split in half. The geneticists also studied several outgroup species (not shown) to compile a likely ancestral DNA sequence. From this information, they have constructed four possible phylogenetic trees. Based on this genetic information, which phylogenetic tree is most parsimonious? a) phylogenetic tree I b) phylogenetic tree II c) phylogenetic tree III d) phylogenetic tree IV

C) A dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid cross involves only one. D) A monohybrid cross is performed for one generation, whereas a dihybrid cross is performed for two generations. E) A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio.

Which statement about crustaceans is true? *(A) all have the same number of appendages

(B) all have an internal skeleton

(C) all have an exoskeleton

(D) only some have jointed appendages

Answers

Answer:

C. All have an exoskeleton

Explanation:

Crustaceans is a subphylum

of Arthropoda. The study of crustaceans is knows as carcinology or crustaceology.

They are important sources of food and they consist of crabs, crayfish, prawns etc. They are closely related to insects in terms of morphological(structural) features.

Crustaceans have varying numbers and structure of appendages. However they lack endoskeletons and possess exoskeletons.

Why do living things use enzymes instead of heat as a source of activation enegry

Answers

Generating heat in order to start a reaction uses energy to begin with.  Enzymes however reduce the activation energy and can only function (usually) within a narrow temperature range, using less energy.  Enzymes are used because they are more efficient.

Animals in the tundra struggle to find food and keep warm.
a. True
b. False

Answers

The answer is a. True.

In tundra, there is no trees, only shrubs, grasses, mosses, lichens. There is very cold, windy and rainy and a food is reduced. Animals in the tundra are adapted to these harsh conditions. Migration or hibernation can be the way to adapt to tundra. Many animals have hollow fur with trapped air inside, so it serves as an insulation layer and keeps them warm. Some animals have shorter ears and mouth to reduce the escape of body heat. Regarding the food, food eaten by summer is stored as a layer of fat under the skin. Caribou, for example, is able to digest lichens. So, it is a struggle to live in the tundra, but animals adapted in different ways to survive.

Why are small leaves an adaptation in a desert environment?a. They trap less water.
b. They minimize water loss.
c. They absorb more light.
d. They fall out in the winter.

Answers

The desert environment makes it difficult to take in water, so leaves that are small would adapt to the desert environment by trying to conserve the little water that they do receive. Therefore, your answer should be:

b. They minimize water loss.
I think a)they trap less water because in rainforest they have bigger leaves because it rains mmore

Why is it important to sequence your plasmid after purifying it?

Answers

Here is my suggestion. ALWAYS you digest a vector you should do a gel-purification step. Some people will say that they don't do it because it's a waste of time and that is ok, however, if you do it you are practicing good molecular biology as defined by Sambrook&Maniatis, and these guys knew something about it. Therefore, I will encourage you to do this step as often as you can, this will ensure you have no traces of undigested vector that will interfere during your transformation step (e.g. false positive) and consequently save you time later. The best way to save time is to do it right. You also want to get rid of buffers and ions that may (or may not) interfere with your phosphatase steps and have a clear start too. The later is not so critical though, as most reagents are now quite compatible with each other as well as between companies, which is great. Then, after phosphatase treatment the cleaning step depends on two things: if you used CIP (NEB), this enzyme you MUST gel-purify (recommended) or use a kit to get rid of the CIP that tightly binds to the end of your DNA and cannot be heat inactivated. If you used TSAP (Promega) 0r any other thermosensitive phosphatase, then you can heat inactivate it. The next thing to take into account is to check the buffer compatibilities between your recently 'phosphatased' vector, your digested construct and your ligation buffer. Most of the T4 DNA ligase in the market are compatible with any of the buffers for restrictions and phosphatase. For your Insert in the experimental setting you have provided, I believe you can skip it.
