a)what are the difference between two species of minnows?​

Answers

Answer 1

Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through selection. Parasitism and predation induce important mortality and fitness costs, and are thus main candidates to create and maintain personality differences in the wild. Here, we present data on the behavioral consistency of the Eurasian minnow (Phoxinus phoxinus) from two populations that live in different tributaries of the same river, but whose ecological environment differs fundamentally with regard to predation and parasitism. We experimentally demonstrate that individual minnow in both study populations are consistent in their boldness and activity. However, the two study populations differ notably: in the high predation and parasitism risk population fish show higher mean boldness, but tend to be less active than fish in low predation and parasitism risk population. Parasite (Diplostomum phoxini) load was negatively, but not statistically significantly, associated with fish activity level. Our study suggests that parasitism and predation are likely important agents in the ecology and evolution of animal personalities.

what is the point on an object where the force of gravity is considered to act A. center of mass B. top of an object C. middle of the object D. center of gravity​

Answers

Answer:

D. Center of gravity.

Explanation:

Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.

Answer:

Explanation:

Answer:

The correct answer is c, plz give me brainlest

Explanation:

got 100 percent on the quiz

A property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

What is Radioactive dating?

Radioactive dating may be defined as a type of methodology for dating rocks and minerals with the help of radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.

Potassium-argon dating is a method of determining the time of origin of rocks by estimating the ratio of radioactive argon in order to radioactive potassium in the rock. This dating method is typically based on the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks.

Therefore, a property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

Sickle cell anemia is a genetic disease that affects the red blood cells. Your red blood cells are typically donut shaped
and have the job of carrying oxygen around your body. In people with sickle cell anemia, the blood cells become
crescent-shaped and are thick and sticky. They are not as able to carry oxygen, and can even get clogged in the blood
vessels blocking the flow of blood, and therefore oxygen to organs, causing pain and organ damage.
Sickle cell is caused by a genetic mutation that changes a single glutamic acid to valine in the 6 th amino acid position.

Examine the codon chart provided above (for #s 3-5), and determine what mutation likely occurred to cause the
change from glutamic acid (GLU) to valine (VAL). To help get you started, it is helpful to know that a person with

Cone-bearing plants have two types of cones: female cones and male cones. Reproduction begins when one of the pollen grains from inside a pollen sac on the male cone floats through the air to the scale of a female cone. A pollen tube then grows from the pollen grain toward the female ovule.

Leukemia is a malignant progressive disease in which the bone marrow and other blood-

A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.

Answers

Answer:

A Dysfunctional checkpoints may lead to abnormal cell growth.

Explanation:

One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.

There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

By

Mary Simpson

This flower must have grown in neutral soil, with little aluminum.

In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

an increase in the concentration of protons in the cytosol will most likely have which of the following effects on glycolysis

Answers

Answer:

Reaction rate will increase as a result of the increased H+ concentrate

Explanation:

Because the more ions the faster the reaction rate

The increase in the concentration of protons ; increases the Reaction rate

An increase in the number the positive ions ( H⁺ ) in a reaction will lead to an increase the reaction rate and a decrease in the activation energy.

Therefore as the number of protons ( H⁺ ) in the cytosol increases, the ripple effect it will have on glycolysis will be an increase in the rate of reaction ( i.e. Reaction rate ) and a decrease in activation energy.

Hence we can conclude that an increase in the concentration of protons in cytosol will increase the Reaction rate of glycolysis.

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

Answers

Answer:

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic

Explanation:

Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

     -this is a plant cell because of the cell wall

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

     -prokaryotes don't have DNA contained in a nuclear membrane

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

     - DNA contained in a nuclear membrane --> eukaryototic

     - cell wall --> plant cells, which are eukaryotic

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

      -DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

What is function of fertilizer ?

An additional organic or inorganic substances which is added to soil or plants to increase the crop productivity is called as fertilizer.

It contain plant growth promoting nutrients like nitrogen, potassium, and phosphorus; For example, urea, anhydrous ammonia, etc.

The organic fertilizer is derived naturally from plants and animals. It enriches the soil nutrient level, encourage microbial reproduction.

Organic fertilizers are Agricultural Waste, Manure, municipal sludge etc.

Inorganic fertilizers generated chemically contain inorganic nutrients for crop growth; It can be up two types.

Nitrogen fertilizers where nitrogen is the primary element as it is constituent of chlorophyll, maintain the process of photosynthesis, thus improve the crop production.

Phosphorus fertilizer, increases the plant root growth as the protoplasm of the cell contains phosphorus, important for cell growth and proliferation.

Thus, option A is correct.
