calculate the weight of an object whose mass is 30 kg and acceleration due to gravity 10 m/s2
Answer:
300 N
Explanation:
[tex] m = 30 \: kg \\ g = 10 \: m {s}^{ - 2} \\ w =? \\ \because \: w = mg \\ \therefore \: w = 30 \times 10 \\ \therefore \: w =300 \:N \:(Newton) [/tex]
The weight of the object having a mass of 30 Kg is 300 N
The weight and mass of an object are related according to the following equation:
W = mgWhere:W is the weight
m is the mass
g is the acceleration due to gravity.
With the above formula, we can obtain the weight of the object as follow:Mass (m) = 30 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?W = mg
W = 30 × 10
W = 300 NTherefore, the weight of the object is 300 N

All of the following are physical characteristics used to determine race except
a. skin color
C hair texture.
b. eye color
d. body structure.
The physical attributes that are used to determine race may not include body structure.
Body structures are generally influenced by the environment that a person lives or what they do irrespective of whether it is genetic or otherwise.
Skin color, hair texture, and eye color, however, are determined by genes located on human chromosomes. Thus, these attributes give an indication of the race that a person belongs.

treatment, prevention, or cure ?
Answer:
- Epidemiologists and bioinformaticians predict the waves of the pandemic
- Geneticists discover the molecular mechanisms involved in pathogen infection and replication
- Molecular biologists and biomedical researchers develop therapeutical strategies for treating these pathologies
Explanation:
The interdisciplinary teams are groups of professionals from different fields that work in a coordinated manner toward a common objective, in this case, for the treatment of infections caused by pathogenic organisms. An interdisciplinary team formed by members from different biology research areas (i.e., geneticists, virologists, bioinformaticists, etc) are able to work collaboratively with the same purpose to get results that are otherwise impossible.

It could lead to a build up of fluids and cause your feet to swell. Your hair becomes brittle and falls out. Your nails become brittle. Eating less proteins puts you a a higher risk of high blood pressure. Your muscles get weaker. And your skin gets flaky.
Explanation:
Explain cancer in terms of the cell cycle
Answer:
hey mate this is your answer
Explanation:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Cancer is the result of unregulated cell division caused by a breakdown of the processes that govern the cell cycle.
What are oncogenes?A gene that has the potential to cause cancer is known as an oncogene. These genes frequently exhibit mutations or are highly expressed in tumor cells.
When crucial functions are altered and malfunctioning, the majority of healthy cells will die quickly and according to a predetermined schedule.
Uncontrolled cell division brought on by a breakdown in the mechanisms that control the cell cycle results in cancer.
The loss of control is caused by a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Incorrect instructions will cause a protein to malfunction.
Thus, due to unregulated cell cycle, cancer becomes prominent.

El Niño is caused by __________. A) ocean currents B) the isolation of continents C) orography D) all of the above
Answer:
A) ocean currents is correct
Explanation:
El Niño is caused by ocean currents. So, the correct option is (A).
What are Ocean currents?An ocean current is a type of continuous, directed movement of ocean water that is generated by a number of forces acting on the water including wind, the Coriolis effect, breaking waves, cabling, and temperature and salinity differences.
These can be caused by density differences in air, water masses that occur due to temperature and salinity variations, gravity, and events such as earthquakes or storms. These are continuous streams of sea water that spread through the ocean.
An El Niño condition typically occurs when surface waters in the equatorial Pacific become warmer than average and easterly winds become weaker than normal.
Thus, El Niño is caused by ocean currents. So, the correct option is (A).

Conservation biologists studying cheetah populations have determined that the lack of genetic diversity among the cheetahs is due to
genetic drift.
Which statement explains the most likely consequence of having a low genetic diversity on the cheetah population?
O A. The chances of a mutation occurring in the cheetah population are decreased, increasing the cheetah survival rate.
OB. The gene pool remains in equilibrium and future generations of cheetah offspring are stronger and better adapted to their
environments.
O C. The cheetah population becomes less likely to survive an outbreak of a disease or an environmental change, increasing the chance
of species extinction.
O D. Genetic variability is maintained from older cheetah populations that have survived and endured environmental stressors.
Answer:The correct answer is C
Explanation:
I did the test
The statement that described the most result of less genetic diversity should be option c. where the cheetah population should be less likely to survive.
What is genetic diversity?It means the range where the various inherited traits lies within a species should be considered. In terms of species, there should be high genetic diversity. Also, it contains various individuals that contains various traits. It should be important for the population for adapting the changing environment.

Answer:
Designing some instruments does help science, but it doesn't advance ideologies of science.
Explanation:
Science is based on theories and laws. Scientists are constantly trying to explain the concepts of the universe by ideas. Sure, instruments do help scientists gather information and such, but ideas and philosophies, theories and laws are the ones that are most important. Without new ideas in science, we would not be able to hypothesize many things, or even develop new instruments.

What is a chromosome?
A chromosome is a thread-like structure found in the nucleus of cells that carries genetic information in the form of genes. Chromosomes are made up of DNA, which is a chemical compound that contains the instructions for the development and functioning of all living organisms.
In most organisms, chromosomes are arranged in pairs, with one chromosome of each pair inherited from each parent. The complete set of chromosomes in an organism is known as its genome. The genome of an organism contains all of the genetic information necessary for the organism to develop, grow, and function.
Chromosomes come in different sizes and shapes, and the number of chromosomes can vary among different species. For example, humans have 23 pairs of chromosomes, for a total of 46 chromosomes, while dogs have 39 pairs of chromosomes, for a total of 78 chromosomes. The number and arrangement of chromosomes can play a role in the characteristics and traits of an organism.
