Explanation:

The statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis. So, the correct option is B.

It is a complex molecule that contains all the information necessary to build and maintain an organism. It stands for Deoxyribonucleic acid. It is considered the genetic material in most organisms.

The skin cells in the G1 phase have an average of 12 picograms of DNA. As the amount of DNA in the G1 phase is 2C, hence 2C = 12 pg of DNA.

Now in the same organism, a cell from gonadal tissue is identified and that single cell contains 6 pg of DNA, which means, the amount of DNA is 6 pg that is C. Therefore, after the completion of meiosis, the cell contains half the amount of DNA as compared to the parent cell in G1.

So, Amount of DNA = C = 6 pg.

Therefore, the statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis.

Explanation:

diploid cells are cell that have 2 genetic alleles, one from your mom and one from dad, so all your cells are diploid, except haploid cells in the rep system.

Answer:

Explanation:

DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

Answer:

The Carbonic-Acid-Bicarbonate Buffer. In animals with lungs, the carbon / bicarbonate buffer system is especially effective. In these animals, the H2CO3 in the blood plasma is in equilibrium with the gaseous CO2 present in the airspace of the lungs, which represents a practically unlimited reserve of CO2 that can participate in the equilibrium.

Explanation:

In the Carbonic-Acid-Bicarbonate buffer system, 3 reversible equilibria take place between the CO2 gas in the lungs and the bicarbonate dissolved in the blood. The bicarbonate ion (HCO3-) can combine with a proton (H +) to form carbonic acid (H2CO3), thus absorbing protons from solution and raising blood pH. Carbonic acid, which can be formed from CO2 and water, can dissociate into H + and HCO3- to provide H + and lower blood pH. Carbonic acid, which can be formed from bicarbonate, is converted to CO2 and water by a very fast enzymatic reaction. CO2, being volatile, can be rapidly eliminated from the body in variable amounts through respiration.In the clinic, the system that is measured for the assessment of the acid-base status is the carbonic / bicarbonate system.

Substitution of other materials for wood products

Recycling of paper products.

Expansion of farming

Explanation:

To decrease the rate of deforestation, we have to make a substitute of other materials for the wood products in order to lower the demands of wood. Recycling of paper and other wood products which can be used again that reduces the demands of wood and lowers the cutting of trees. If we expand the farming of trees for the wood purpose, so we can fulfill our needs of wood and there is no need for the cutting of trees for fulfilling the demand of the wood.

Explanation:

Fermentation is the process of breaking down substances different types of bacteria or microorganisms will producing heat, this process can also be completed without the usage of oxygen. Finally, fermentation is used to create alcohol like wine or beer which is considered wastes to the body. Therefore options one, three, and four are your answers or "process that breaks down larger molecules  into smaller molecules, energy for the body process that does not rely on the presence of  oxygen, and process that creates waste products."

Answer: The sequence of bones and joints that convey the forces include: From metacarpal bones --> carpal bones --> midcarpal and radiocarpal joints --> radius and ulna bones --> elbow joint --> humerus --> glenohumeral joint --> scapula --> acromioclavicular joint --> clavicle --> sternoclavicular joint --> sternum.

Note: the sign (-->) represents "into the".

Explanation:

The skeletal system is made up of bones of the skeleton, their joints and the skeletal muscles which acts together to bring about different movements in the body. The skeleton of a vertebrate had the following basic plan:

--> The axial skeleton: this forms the main central axis. This is made up of the skull,vertebral column, breastbone (sternum), and ribs.

--> The appendicular skeleton: this consists of parts that articulates with the axial skeleton. This is made up of the forelimbs, hindlimbs, pelvic and pectoral girdles.

From the question given, in an attempt to help push the friend's car, the sequence of bones and joints that convey the forces will pass from METACARPAL BONES of your hand into the CARPAL BONES at the base of your hand. Forces will then pass through the MIDCARPAL and RADIOCARPAL JOINTS into the RADIUS and ULNA bones of the forearm. These will pass the force through the ELBOW JOINT into the HUMERUS of the arm, and then through the GLENOHUMERAL JOINT into the SCAPULA. The force will travel through the ACROMIOCLAVICULAR JOINT into the CLAVICLE, and then through the STERNOCLAVICULAR joint into the STERNUM, which is part of the axial skeleton.

As one pushes against the car, the forces will pass in a sequential manner from the bones of the hand to the bones that are part of the axial skeleton.  

• Forces will pass from the metacarpal bones of the hand into the carpal bones at the base of the hand, when one pushes against the car.  

• After that the forces will then mediate via the radiocarpal and midcarpal joints into the ulna and the radius bones of the forearm.  

• Then the force will move via the arm's humerus, and then via the glenohumeral joint into the scapula.  

• The force then will mediate via the acromioclavicular joint into the clavicle, and then via the sternoclavicular joint into the sternum, that is, the part of the axial skeleton.  

Thus, in the given case, force gets mediated through the bones of the hand and towards the bones of the axial skeleton in a sequential manner.

Answer:

3.5 cm

Explanation:

Mass of mercury = 3.380

Diameter = 0.200

At t = 0 and 25 degrees we have 13.596 and 13.543 as density

At 0 degree = v = 3.380/13.596 = 0.2485

At 25 degrees = 3.380/13.534 = 0.2497

We use volume of cylinder to get height

At 0⁰ height = 7.91

At 25⁰ = 7.944

The difference in height = 0.035

Multiply by 100 = 0.35 x100

= 3.5cm

Answer:

D. Due to the availability of solar energy, Diatom mass peaks in July.

Explanation:

Diatom are the photosynthetic algae which prepare food for themselves from the solar radiation just like plants. These diatoms produce more biomass or vegetation in the summer season mainly in July because availability of more sunlight in the Barents sea region while on the other hand, less biomass in the winter season due to low temperature and solar radiation which also effects the population of zooplankton organisms. So we can conclude that seasonal changes have a great impact on the organisms living around the Barents Sea.

Answer:

The availability of solar energy limits photosynthetic productivity in winter months
