A new mammal has been discovered in the thickly-forested mountains of Papua New Guinea. The squirrel-like animal lives in the canopy of the forest and has a diet rich in leaves. On occasion, however, the animal drops to the ground to quickly fill its cheeks with its own fecal droppings, for ingestion once it is safely back in the trees. The GI tract of this animal would most likely include ________. a simple stomach and a large cecum a simple stomach, a short small intestine and colon, and a small cecum a four-chambered stomach and long intestines a long small intestine with abundant villi and an appendix at the beginning of the large intestine a short intestine and no cecum
Answers
Answer:
a simple stomach and a large cecum
Explanation:
Some small animals whose diet is prominent in vegetable matter, have an elongated cecum.
This segment of the digestive tract might be considered the first portion of the large intestine. It receives undigested material, and through the action of bacterial flora, is able to ferment this material and mix its contents with mucous substances to facilitate absorption. Through the walls, the organ can absorb fluids, salts, and nutrients.
The cecum size varies according to the animals. In small organisms, such as the new squirrel-like herbivore animal from the example, the cecum is enlarged. An elongated surface is useful for better digestion and absorption.

Gymnosperms are a group of higher plants that produce naked seeds i.e. seeds not cased by a fruit. Pteridophytes are a group of lower plants that have vascular bundles.
WHY ARE GYMNOSPERMS ADVANCED THAN PTERIDOPHYTES?
Gymnosperms bear seeds while pteridophytes bear spores (seedless)Gymnosperms do not require water for fertilization to occur while pteridophytes require water for their fertilizationGymnosperms have a well developed root system while pteridophytes do not have a well developed root system (they use rhizoids)Gymnosperms exhibit secondary growth while pteridophytes do notGymnosperms undergo pollination while pteridophytes do not.Learn more at: https://brainly.com/question/10517712

a) Every cell of their body contains a gain-of-function allele of an oncogene
b) Most cells in their body contain multiple cancer-causing mutations
c) If they get malignant cancer, somatic mutations will not have been a factor
d) Their cancer will most likely arise in their germ cells, not their somatic cells
e) None of the answers effectively describes the situation
f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
Answers
Answer:
Every cell of their body contains defective , loss of function allele of a tumor suppressor gene
Explanation:
Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers
Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.
The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

Rainforest plants live in a warm humid environment that allows an enormous variation rare in more temperate climates: some like the orchids have beautiful flowers adapted to attract the profusion of forest insects.
Competition at ground level for light and food has lead to evolution of plants which live on the branches of other plants, or even strangle large trees to fight for survival.
The aerial plants often gather nourishment from the air itself using so-called 'air roots';. The humidity of the rainforest encourages such adaptations which would be impossible in most temperate forests with their much drier conditions.

Based on your own investigation, what challenges do you think scientists face when classifying new organisms?
Answers
The main challenge that scientists face in classifying new organisms is that some organisms may show properties that are intermediate between the properties of known classes of organisms.
What is taxonomy?Taxonomy is the hierarchical system whereby scientists classify organisms based on the characteristics of the organism. New organisms are studied and classified accordingly.
However, new organism may show properties that are intermediate between the properties of known classes of organisms thereby posing a problem for the classification of such organisms.

The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answers
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer
