Predict how the coleoptile will grow (or not grow) under each treatment by dragging the labels onto the table. labels may be used once, more than once, or not at all.

Answers

Answer 1

The regulation of plant growth is the role of different plant hormones and regulators of plant growth, predominantly the hormones Auxins, which are located at the tip of the coleoptile. Depending on the environment the plant is growing in, and the amount of Auxins the plant contains, plant growth is determined.

So there is a compound in the tip of the coleoptile that is responsible for the plant growing vertically in the dark or the plant growing towards the light directionally. To answer your question, we need to look at the different circumstances the plant is growing in. What's important here is that it has been shown that agar is permeable to chemical compounds produced in the coleoptile tip, but the mica is not.

The intact coleoptile has the intact amount of growth hormones in the coleoptile tip, so it will grow tall and straight in the dark, and tall and bent with directional light treatment.

The cut coleoptile (tip removed) doesn't have growth hormones that are located in the tip (the tip has been removed), so it will grow short and straight regardless of its environment.

The cut coleoptile with mica insert, which is not permeable to the compounds in the tip of coleoptile, would grow short and straight in both a dark environment and with directional tight treatment.

The cut coleoptile with agar insert would grow tall and straight in the dark, and tall and bent with directional light treatment, since agar is permeable to the compounds found in the tip of the coleoptile which ensure the growth of the plant.

Final answer:

The question involves understanding experimental design in Biology, where row 2 of corn without fertilizer acts as the control group in a plant growth experiment.

Explanation:

The subject of this question pertains to experimental design in Biology, specifically regarding plant growth experiments. When the scientist applies fertilizer to row 1 but not to row 2, with all other conditions being equal, row 2 serves as the control group.

This control is essential for understanding the effect of the fertilizer on plant growth. In experiments where different variables are tested on their effects on plant growth, such as light exposure, nutrition, or genetic factors, the control group provides a baseline for comparison. The control group's outcome is used to assess the impact of the independent variable being tested, which in the case of the scientist's experiment with corn, is the fertilizer.

Explanation

Endogamous is a term used to refer to the practice of some group of individuals who radically rejects the incorporation of individuals outside their group or community. Also, this refers to an attitude of communities that prevent members of other groups from associating or joining in marriage, reproduction, or other relationships with members of their group.

This practice was very common in antiquity because it allowed power to be kept within the same family or to maintain the purity of a supposed race. So, the correct answer is D. Endogamous.

Ruminants refer to a category of herbivorous mammals, they are hoofed, toed mammals that consume food in bulk and digest afterward. For example, sheep, cow, goat, camel, giraffes, and others.

The main characteristic of ruminant mammals is their chambered stomach. The ruminant stomach has four chambers, that is, the reticulum, rumen, abomasum, and omasum. The reticulum refers to the second chamber of the ruminant stomach. It exhibits regular contractions that precede the biphasic ruminal contraction for digestion of food particles.

Which specific term describes teeth with two ridges, as found in old world-monkey molars?

Answers

Old-world monkeys had specifically shaped molars, which are called bilophodont molars. Molars are big teeth in the back of the mouth that are used for grinding food and crushing it into small pieces that are easier to digest. They are very diverse in regards to size and shape in different groups of mammals.

The old-world monkeys had molars with two transverse ridges, so the name bilophodont broken down is "bi" which means "two", and "loph" which means "ridge", while "dont" of course means "tooth". So the name "bilophodont" refers to a tooth that has two ridges.

Final answer:

Teeth with two ridges found in Old World monkey molars are described as 'bilophodont.' This distinctive feature of the molars in Cercopithecoidea aids in processing their omnivorous diet.

Explanation:

The specific term that describes teeth with two ridges, as found in Old World monkey molars, is “bilophodont.” This term refers to the most distinctive feature of the molars belonging to the Cercopithecoidea, a group within the Catarrhini which includes Old World monkeys. These molars exhibit two parallel ridges that are adapted for their omnivorous diet, which often includes a variety of fruits and leaves.

Within the Phylum Chordata, specifically among the class Mammalia, Old World monkeys have adapted these bilophodont molars for processing different kinds of foods, efficiently crushing and grinding their food for digestion. Understanding the dental structures of primates like Old World monkeys aids in the study of their dietary habits and evolutionary history.

what evolutionary feature would distinguish phytoplankton from zooplankton?

Answers

The evolutionary feature that would distinguish phytoplankton from zooplankton is: nutrition and cellular structure.

Evolutionary Feature:

Phytoplankton and zooplankton are two distinct groups of plankton that play crucial roles in aquatic ecosystems, and they can be differentiated primarily by their evolutionary features related to nutrition and cellular structure.

Key Evolutionary Features

1) Nutritional Mode

Phytoplankton are autotrophic organisms, meaning they can produce their own food through photosynthesis or chemosynthesis. This ability allows them to convert sunlight or chemical energy into organic matter, making them primary producers in the aquatic food web. They are typically plant-like and include groups such as diatoms, dinoflagellates, and cyanobacteria.

Zooplankton, on the other hand, are heterotrophic, which means they cannot produce their own food and must consume other organisms, primarily phytoplankton. They are considered consumers in the food chain and include a variety of organisms such as crustaceans (like copepods and krill), protozoans, and larval stages of larger animals.

2) Cellular Structure

Phytoplankton possess chlorophyll and other pigments that enable them to capture light energy for photosynthesis. Their cellular structure is similar to that of plants, containing chloroplasts and a rigid cell wall, which can be composed of silica (as in diatoms) or cellulose (as in green algae).

In contrast, zooplankton lack chlorophyll and do not have the cellular structures necessary for photosynthesis. Their cells are typically more complex in terms of mobility and sensory structures, allowing them to navigate through water and respond to environmental stimuli.

Hello. This question is incomplete. The complete question would be:

"A farmer was growing the peas seen here: round and yellow are dominant traits; green and wrinkled are recessive traits. The farmer's goal was to produce a crop of round, green peas. To do this, she introduced plants that bred true for green seeds (peas). Over time the gene pool was modified and the presence of yellow peas became non-existent. This change in the gene pool is a result of hybridization. In scientific terms, we could call this a method of A) gene flow. B) emigration. C) niche shift. D) genetic drift. "

Answer:

A) Gene Flow

Explanation:

Gene flow is nothing more than the movement of genes from one population to another. This can be seen in the question above, where the farmer introduced a population of plants that had the characteristic he wanted in the existing plant population with the goal of transferring genes from one population to another.

This flow, also called migration, is ensured by the insertion of new genes in a population thanks to the arrival of new individuals. Gene flow therefore ensures that populations are less genetically differentiated.

Gene flow is an important factor related to genetic variability. If an individual from one population migrates to another and inserts his or her gene into the population, if not an existing gene, it provides increased genetic variation.
