The SI base unit of mass is the kilogram (kg), which was historically based on a physical object but has been redefined in 2019 in terms of the Planck constant to maintain its stability over time. A kilogram is about 2.2 pounds, and a gram is 1/1000th of a kilogram.

The SI base unit of mass is the kilogram (kg). Historically, it was defined by a platinum-iridium cylinder, known as the International Prototype of the Kilogram (IPK), which was stored at the International Bureau of Weights and Measures near Paris. However, in May 2019, the definition was revised and is now based on fixed numerical values of the Planck constant and other fundamental physical constants. This redefinition ensures that the unit will remain stable over time, unlike the IPK which could lose or gain atoms, and thus mass, over time.

Laboratories commonly use balances for measuring mass, which must be calibrated using a standard mass to ensure accuracy. The kilogram is pivotal in making mass comparisons because all other masses are ultimately compared to it. As of 2019, with the advancement in science and technology, a more accurate way of defining a kilogram using the Kibble balance and Planck's constant has been adopted.

A kilogram is equivalent to about 2.2 pounds, and a gram is exactly 1/1000th (10-3) of a kilogram. These measurements fall under the metric system widely used in scientific and engineering contexts.

Answer:

The rock will be old between 360 and 290 million years

Explanation:

If we have fossils from both nautilus and goniatite in the same rock layers, then we can look at the periods in which these two animals lived as a clue about the age of the rocks, thus the animals themselves as well. The nautilus occurs in the fossil records around 410 million years ago, but it is not extinct, in fact it still exists and it is one of the oldest species on the planet. The goniatite has had different story, as it existed for around 70 million years, between 360 and 290 million years ago. We can see from this information that these two organisms coexisted throughout the whole existence of the goniatite, thus the rocks can have an age of anywhere from 360 to 290 million years.

Answer:

c. Presence of predators

Explanation:

The presence of predators can cause natural selection to occur. In the presence of predators, individuals with advantageous traits such as faster speed, better camouflage, or stronger defenses are more likely to survive and pass on their genes to the next generation. Hence option c is correct.

Natural selection is the process by which certain traits or characteristics become more or less common in a population over time due to their impact on survival and reproduction.

As a result, the frequency of these traits increases in the population, leading to an overall change in the population's genetic makeup.

The mechanism of natural selection was first proposed by Charles Darwin as part of his theory of evolution by natural selection. Darwin observed that individuals in a population vary in their traits, and those with traits that help them survive and reproduce are more likely to pass on their genes to the next generation.

Over time, this can lead to the evolution of new species, as advantageous traits accumulate and become fixed in the population.

Therefore the correct option is C the presence of predators.

Answer:

Osmosis is the chemical process.

Explanation:

Osmosis is the chemical process, where the solution moves from higher concentration to lower concentration through a semipermeable membrane. Osmosis may be slow or reversed, where the movement of solution is occured against the concentration gradient, from lower to higher concentration. Osmosis is similar to diffusion. Diffusion follows the same process as in osmosis without semipermeable membrane.

There are three types of osmotic solution:

Final answer:

Fat cells are larger than red blood cells because they store energy as fat, which takes up significant space within the cell, while red blood cells are small and shaped to efficiently transport oxygen.

Explanation:

Fat cells, or adipocytes, are much larger than red blood cells due to their function in the body. Adipocytes are specialized to store energy in the form of fats; they contain large fat droplets that occupy most of the cell's volume. In contrast, red blood cells, or erythrocytes, are designed to maximize their oxygen-carrying capacity. Erythrocytes are small and have a biconcave shape to increase the surface area for oxygen transport. They lack a nucleus and most organelles to provide the maximum space for hemoglobin, the protein that binds to oxygen.

Besides serving as energy reserves, adipose tissue offers insulation from cold temperatures and mechanical protection. The adipose tissue, rich in capillaries, allows for rapid mobilization and storage of fat molecules. In contrast, erythrocytes are designed for a different purpose entirely—they transport oxygen through the blood to various parts of the body and are produced in the marrow of bones, living for about 120 days before they are destroyed.

Explanation: There where not many trees in the plains and with so many Giraffes roaming around with little predators, food was hard to come by. As the lower branches started thinning out, only the taller giraffes could reach the higher branches. When there was no food left, the shorter Giraffes started to die off, leaving only the taller giraffes. This is known as Survival of the Fittest because only Giraffes with the taller gene where able to survove. The shorter gene is extinct now becasue they no longer had food to live off of.

Answer: Polar substance, it dissolves polar substances, also called hydrophilic.

Explanation:

Water is a polar molecule and forms hydrogen bridges. Water is considered the universal solvent because it has great dissolving power. As water is a Polar substance, it dissolves polar substances, also called hydrophilic. Nonpolar substances, like oils, are hydrophobic and do not mix with water. The water is cohesive. Due to the formation of hydrogen bridges, water molecules attract strongly, keeping the substance stable. Also, water attracts other polar molecules, an association mechanism. That's why water wets polar materials like cotton and paper.

Explanation:

Adult stem cells can only differentiate to form a single type of cell.

Embryonic stem cell are pluripotent as they can differentiate into any cell types except extra embryonic membranes like placenta.

Only zygotic stem cells are totipotent

Adult stem cells differ from embryonic stem cells as Adult stem cells have unipotency, and embryonic stem cells have pluripotency.

Unipotency: A unipotent cell is that one stem cell that has the capacity to differentiate into one cell type only.

Pluripotency:  pluripotent cell that has the potential to differentiate into any cell of the three germ layers i.e  endoderm ( stomach lining, gastrointestinal tract, the lungs etc), mesoderm (muscle, bone, blood, urogenital etc), or ectoderm (epidermal tissues and nervous system etc), but not into cells of extra-embryonic tissues like the placenta.

Adult Stem Cells are unipotent that is they can develop only one type of cell but Embryonic Stem Cells are pluripotent, Hence, can develop into any cell type.

The answer is D. The moon’s surface reflects sunlight.

The moon appear to shine its own light because the moon's surface reflects sunlight which is in option D as moon does not emit its own light like a star. Instead, it appears to shine because it reflects sunlight.

The intensity of the moon's reflected light can vary depending on factors such as the moon's position in its orbit and the angle at which sunlight hits its surface. This is why the moon appears to change in brightness throughout its lunar cycle, which we observe as the different phases of the moon. It's important to note that the moon's atmosphere is extremely thin compared to Earth's atmosphere, and it does not have the ability to scatter or reflect sunlight in the same way Earth's atmosphere does.

Answer: DNA evidence

Scientists more accurately estimate the point of divergence in evolutionary relationships using molecular clocks and phylogenetic trees constructed from morphology, fossil records, and genetic data, which can include DNA analysis and protein sequence comparison.

Scientists can estimate more accurately at what point various groups of organisms diverged evolutionarily from one another by using molecular clocks and analyzing phylogenetic trees. Molecular clocks use DNA sequences to estimate relatedness among species and determine when species diverged from a common ancestor. Phylogenetic trees are constructed using combined data from morphology, fossil records, and genetic information. These trees represent hypotheses of evolutionary relationships, and they continue to evolve with new discoveries and data.

By identifying homologous characteristics—traits that are similar due to shared ancestry—scientists can discern evolutionary connections between organisms. Using techniques like cladistics and applying the concept of maximum parsimony, scientists can determine the evolutionary timeline that suggests the simplest and most probable path of divergence.

Comparative data from the fossil record and molecular structures, such as DNA nucleotide sequences or amino acid sequences in proteins, enhance the accuracy of these estimates. Moreover, evolutionary investigations combine morphologic and genetic evidence to uncover the evolutionary history of life forms, contributing to the broader understanding of the 'tree of life.'

A Autotroph derives its nutritional requirements from simple organic substances.

Explanation:

Answer:

AUTOTROPH: trees, algae carrots

HETEROTROPH: tiger, deer, human

Answer:

Option (C)

Explanation:

When many trees are removed from any area, the area becomes dry and gets adversely affected. Due to the lesser amount of trees, the area will evaporate more due to its dry and increasing temperature, as a result of which there will be more precipitation. This precipitation will lead to more amount of surface runoff over the area. So the transpiration will simultaneously decrease as the plants will not be able to absorb water by its roots, that regulates the overall temperature of the plant and protects it from dying.

Thus, the transpiration process is directly proportional to the number of plants and trees in any area.

Thus, the correct answer is option (C).

Answer:

the answer is Surface

Explanation:

Wind creates surface currents by dragging a layer of water when it passes over the water’s surface. This differs from deep ocean currents which are mainly driven by temperature and salinity differences.

Surface currents are oceanic currents that occur at or near the surface of the ocean, and they are primarily driven by the wind. These currents are responsible for moving large amounts of water horizontally across the ocean's surface. Wind interacts with the surface of the ocean, creating friction and causing the water to move in the same direction as the wind.

When the wind blows across the surface of the ocean, it imparts its energy to the water, generating these surface currents. The direction and strength of surface currents depend on factors such as wind speed, wind duration, and the geography of the ocean. These currents can have a significant impact on various aspects of the marine environment, including climate, marine life, and navigation.

So, in the sentence "The wind stirs up surface currents," the word "surface" indicates that the wind's action primarily affects the currents near the surface of the ocean.
