Why do the cells used for reproduction only have half (½) of the DNA that other cells have?

Answers

Answer 1

Answer:

Because each chromosome has a pair, these cells are called "diploid" cells. On the other hand, human sperm and egg cells have only 23 chromosomes, or half the chromosomes of a diploid cell.

A.Geologists use only one type of radioactive dating.
B.Geologists compare parent and daughter elements to determine rock type.
C.Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
D.Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.

Answers

Answer:

D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.

Explanation:

Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

1) What is the independent variable?
2) What is the dependent variable?
3) What is the experimental group?
4) What is the control group?
5) What is one constant from the experiment above??

Answers

Answer:

Independent variable: type of instrument

Dependent variable: Number of rabbits attracted

Experimental group: The group when he played an instrument

Control group: The group when not playing an instrument

Constant: Same song

Explanation:

1. Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the variable that is changed is the TYPE OF INSTRUMENT used (clarinet, flute, guitar), hence, it is the independent variable.

2. Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the "NUMBER OF RABBITS ATTRACTED" by the instrument played.

3. Experimental group is the group of an experiment that receives experiment treatment, which is the independent variable. In this case, the experimental group is the GROUP IN WHICH INSTRUMENT WAS PLAYED.

4. Control group is the group that does not receive the experimental treatment. In this case, the control group is the group in which INSTRUMENT WAS NOT PLAYED.

5. Constants are those variables that remains unchanged for all groups throughout the experiment. In this case, one constant is the SAME SONG played.

Explanation:

Brainliest? plz

Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.

What is electric fish?

An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.

The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.

If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.

-Chemical energy is converted to mechanical energy that's used for muscle movements.
-Radiant energy is converted to mechanical energy that's used for muscle movements.
-Heat energy is converted to mechanical energy that's used for muscle movements.

Answers

Heat energy is released from the body to the surroundings and Chemical energy is converted to mechanical energy that's used for muscle movements are the  two ways in which energy is conserved when people run.

To do the things you do every day, you need energy. When you eat food, your body can use the chemical energy in the food to move your muscles, allowing you to breathe, walk, run, jump, lift things, and do everything else necessary for survival.

The chemical energy in food is converted into mechanical energy by moving muscles.

Chemical energy in the form of glucose in our food is converted into mechanical energy in the human body during movements such as running or lifting heavy objects. The muscles act as a transducer, converting chemical energy to mechanical energy through muscle contraction.

The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.

Answers

Answer:

According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.

Explanation:

The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.

In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.

I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

They play a vital role in regulating our climate by absorbing carbon dioxide, and help maintain our soil and water.Forests directly support around 1.6 billion peoplenearly a quarter of the world's population. And we all rely on them for the air we breathe and the countless products they provide.But over the last half-century, people have destroyed forests at an alarming rate. We've already lost around half of the world's original forests.The story so farIn the early 1990s, we campaigned to stop the timber industry destroying and degrading the world's forests.At the time, few businesses believed they were responsible for where their timber came from. Those that did claim to sell products from well-managed forests had no way of proving it."Businesses didn't think the environment was their concern," recalls Jean-Paul Jeanrenaud, who led WWF-UK's work on forests at the time."We had chief executives slamming the phone down on us. I even had people threaten to punch me."How things have changed In September 1991, British DIY chain B&Q committed to working with us to buy only legal, sustainable timber. By the end of that year, 16 large UK companies had committed to sourcing their timber products from well-managed forests.That was the beginning of our Global Forest & Trade Network. Today, it's a global partnership of some 275 retailers, producers, community groups and other organizations from across the forest industry supply chain. Members are committed to safeguarding the world's forests and the communities, economies and ecosystems that depend on them.But we needed a way to turn those commitments into reality. So in 1993, we helped form the Forest Stewardship Council (FSC) to certify timber and wood-based products that meet high environmental and social standards.For a forest to be FSC certified, independent inspectors check that it meets the FSC's strict criteria. All trees that are cut down have to be replaced or allowed to re-grow naturally, and parts of the forest are left untouched. The rights of indigenous people are respected, and local workers are employed on a decent salary. Often, companies support other social services, such as schools and clinics.Inspectors also check every stage along the supply chain, so you can be sure that any product that bears the FSC logo is good for forests, people and wildlife.Did you know?Just 10 years ago, only 300 sq km of forest in Russia was FSC-certified. Today, it's 260,000 sq kma quarter of its commercial forests.Facts and stats1.4 million sq kmarea of forest certified by the FSC. That's an area more than twice the size of France81number of countries with FSC-certified forests40 percentforest area of Europe and North America certified by the FSCUS$73bnannual sales of forest-based products by members of our Global Forest & Trade NetworkWhat next?Almost a tenth of forest products traded now meet FSC standards. That's a phenomenal rate of growthbut it means nine-tenths of products are still uncertified.We believe some areas of forest need to be protected from any commercial logging. But we're supporting responsible forestry alongside protected areas to help conserve the world's most important forests:In the Congo Basin, the largest area of tropical forest after the Amazon, 45,000 sq km is now FSC certifiedand we're working with everyone from heads of state on down to increase this. As well as protecting important habitats for elephants, great apes and many other species, sustainable forestry is improving livelihoods for some of the poorest people on the planet.In Borneo, we're working to conserve and restore the "Heart of Borneo," a 220,000 sq km area of the island's species-rich rainforest. Responsible forestry is a vital aspect of this: some 20,000 sq km is already FSC certified or in the process of certification. By 2020, we want the entire Heart of Borneo area to be protected or managed sustainably.In the western Mediterranean, people have sustainably harvested cork for centuries. Cork oak forests provide a haven for rare plants, birds and other wildlife, including the Iberian lynx, the world's most endangered wild cat. We're promoting FSC certification to keep sustainable cork harvesting economically viable and help protect this unique landscape.What you can doYou can help secure a future for the world's forests, and the people and animals that depend upon them next time you buy a tableor any other wood-based product.Only buy products with the FSC labelit's the only credible certification scheme.If you don't see the logo, ask the store or manufacturer why not.
