03 LC) kilogram (kg) is a measurement of which of the following quantity ​

Answers

Kilogram or Kg is a measurement of Mass.

What is Mass?

A physical body's overall composition is measured by its mass. It also measures the body's inertia, or resistance to acceleration in the presence of a net force. The mass of a thing also affects how strongly it attracts other bodies through gravity.

In the SI, the kilogram serves as the basic mass unit (kg). Mass is not the same as weight in physics, despite the fact that weight is commonly determined to use a spring balance instead of a balancing scale and compared directly with known masses.

An object may weigh less than it does on Earth while retaining the same mass due to the reduced gravity on the Moon. This is true because weight is a force, whereas mass is a property.

The model shows the cycling of carbon.
Which part of the model shows carbon moving from the biosphere to atmosphere?

A. The sheep carrying out respiration.
B. Waste materials coming from the sheep.
C. (REFER TO PICTURE!!)
D. The sheep taking in nutrients.

Answers

The sheep carrying out respiration is the correct answer.

The exchange of carbon between the Earth's biosphere, pedosphere, geosphere, hydrosphere, and atmosphere occurs through the carbon cycle, a biogeochemical process. Both biological substances and many minerals, including limestone, mostly consist of carbon.The carbon serves as the model for how carbon moves across the environment and between the many spheres.The process of cellular respiration, carried out by the living world or the organisms, adds carbon dioxide to the atmosphere, which is present in the atmosphere as bound carbon.The sheep engaged in respiration is the right response since cellular respiration is how carbon dioxide gets from the biosphere to the atmosphere.The carbon cycle is one of three cycles—along with the nitrogen cycle and the water cycle—that play a crucial role in the ability of Earth to support life.

Therefore, option A. is correct.

A, equals, 4, π, r, squared
Assuming both cell types are perfectly spherical, how many times larger is the surface area of a crawfish oocyte compared to the surface area of a human oocyte?

Answers

The Crawfish is 400 times larger than the human oocyte.

How to calculate the area?

It should be noted that the radius is given as 1mm.

The surface area is also illustrated as 4πr². The surface area will then be:

= 4 × 3.14 × (1)²

= 4 × 3.14 × 1

= 12.56mm²

The radius of human = 0.05m

The surface area is also illustrated as 4πr². The surface area will then be:

= 4 × 3.14 × (0.05)²

= 4 × 3.14 × 0.0025

= 0.0314mm²

The ratio will be:

= Crawfish / Human

= 12.56 / 0.0314

= 400

In conclusion, the crawfish is 400 times larger than the human oocyte.

Various amounts of table salt are added to water and its affect on density of water is
recorded.
what is the control and experimental group ?

Answers

The control is the source of the water.

What is control?

The control of an experiment is the factor that must be held constant in order for the experiment to be reliable. If these factors are not held constant, then the experimental results are not reliable.

In this case, we are measuring the effect of addition of salt to the density of water. We have to ensure that the water is all taken from the same source so that we can be sure that the density is only affected by the addition of the salt and not other extraneous factors.

(other than: are you a chloroplast? Because you chlorophyll my heart)

Answers

A chloroplast, are you? Because of you, my brain is full of chlorophyll.

Photosynthesis, the process by which light energy is transformed into chemical energy and results in the generation of oxygen and energy-rich organic compounds, takes place in the chloroplast, a structure found inside the cells of plants and green algae. Close cousins of chloroplasts that are free-living are photosynthetic cyanobacteria; according to the endosymbiotic theory, these organisms are the ancestors of both chloroplasts and mitochondria, which are eukaryotic cells' energy-producing organelles.

The chloroplast genome is typically 120–200 kilobases long and circular (although linear variants have also been seen). A growing number of chloroplast genes have been transferred to the genome in the cell nucleus over the course of evolution, significantly shrinking the size of the contemporary chloroplast genome. As a result, nuclear DNA-encoded proteins are now required for the proper operation of chloroplasts.

A diagram of a food web for an African grassland is shown. The greatest competition would most likely occur if which of the following organisms were to decrease?



Question 5 options:

Mice and pangolins

Grasshoppers and impalas

Mongoose and lions

Red oat grass and warthogs

Answers

The greatest competition would most likely occur if grasshoppers and impalas were decreased. Thus, the correct option is B.

What causes competition in a food web?

Competition occurs between different species when individuals of different species struggle to obtain the same resource in an ecosystem such as food or space. Adaptations are the physical and behavior modifications which can help an organism outcompete its competitors.

Impalas are the medium-sized antelopes that roam the savanna and light woodlands of eastern and southern Africa. They are similar to grasshoppers. A decrease in the organisms of grasshoppers and impalas may result into greatest competition in the food web.

True, Enzymes can be used over and over in a reaction. They are not used up.

Enzymes only catalyze the chemical reaction in forward or backward direction

Enzymes may be utilized again to speed up the same process since they don't become damaged or depleted during the reactions they catalyze. Enzymes are incredibly efficient because each one is very specialized for the chemical process it catalyzes.

A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical process in the cell.

Which statements accurately describe the polarity and electronegativity of water?
-The oxygen atom in a water molecule is strongly electronegative.

-Water molecules have slight charges and are attracted to each other by ionic bonds.

-Water molecules are polar and thus associate with each other through hydrogen bonds.

-Covalent bonds in a water molecule bind its oxygen atom to its two hydrogen atoms

-Water is polar, which means that it has an overall negative charge.

Answers

A slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to the properties of water of attraction.

Which statements accurately describe the polarity and electronegativity of water?

Polarity Of Water:

The one oxygen atom and the two hydrogen atoms which are present in a water molecule "H2O" form a polar covalent bond. There is no net charge on water molecule, the polarity of water molecule creates a partial positive charge on Hydrogen and partial negative charge on Oxygen which helps for contributing the attraction force.

Electronegativity Of Water:

A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.

So we can conclude that a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction.

Which statement about properties of Life is false

Answers

Question is incomplete;

The FALSE statement about properties of Life is:

All organisms have the ability to maintain a constant internal temperature.

The claim that all living things have the capacity to maintain a constant internal temperature is FALSE

Different stimuli, such as light, heat, mechanical contact, etc., can cause an organism to react.

Energy is needed by organisms to carry out their metabolic processes (e.g., growth, differentiation, reproduction, etc)

Animals with cold blood, or poikilotherms, are unable to maintain a consistent body temperature regardless of the outside temperature.

Fish, insects, worms, amphibians, and reptiles are examples of poikilothermic animals.

The ability of all creatures to keep a constant internal temperature is, therefore, a FALSE assertion
