D. imprints of organisms known to have lived during a specific time period

Explanation:

The index fossils are very useful to the geologists. These fossils are only found in specific time period. They are also found on lot of locations around the globe, and they are in big numbers. Because of these characteristics, the index fossils are excellent for determining the relative age of rock layers, or other fossils, as they offer the basic information that are needed for this. This type of fossils tend to be small or medium sized ones, as usually the larger organisms do not have very large populations.

Skeletal muscle tissue is responsible for controlling voluntary movements like running or blinking by contracting and moving bones. This action results from the interaction between the actin and myosin proteins within the striated muscle fibers.

Actions completed by skeletal muscle tissue include the control of locomotion and any movement that can be consciously controlled, such as blinking your eyes or running. Voluntary muscle contractions allow our bones to move and are essential for performing all activities of our daily lives. The microscopic structure of these muscles reveals a striated appearance, which is due to the regular arrangement of contractile proteins actin and myosin. When skeletal muscle contracts, it is due to the interaction between these proteins, facilitating movement throughout the body.

Answer:

Half life

Explanation:

The radioactive dating method is usually used to date a rock or a fossil in order to determine its relative age. The unstable isotope elements decays at a certain rate, which normally remains constant and are generally expressed in terms of its half life. Half life is described as the time required by any isotope element to decay half of its original amount. This half life value varies from elements to elements. For example, the half life of Carbon-14 is approximately 5700 years. This half life of an unstable isotope element plays an important role in the radioactive dating method.

Answer:

D. cytoplasm is manufactured

Explanation:

Answer:

36 thymine

Explanation:

DNA is a polynucleotide having double helical structure. The Each helix of DNA is made of nucleotides. Each nucleotide has a pentose sugar, phosphate and a nitrogenous base. Both the helices are joined by corresponding bases through hydrogen bond. The base pairing in the DNA double helix is specific. The purine adenine (A) always pairs with the pyrimidine thymine (T) the purine guanine (G) always pairs with the pyrimidine cytosine (C). Therefore, the number of adenine is 36 then the number of thymine will be 36. Similarly if the number of cytosine is given 24, then the number of guanine will be required 24 not 36.

During photosynthesis, plants use carbon dioxide and sunlight to make sugars and starches. The correct option is option D) carbon dioxide and sunlight.

Green plants, algae, and certain microorganisms transform solar light energy into chemical energy in the form of glucose through a process known as photosynthesis (sugar). Chloroplasts, specialized cell structures predominantly seen in plant leaves, are where this activity occurs.

Sunlight: Chlorophyll, a pigment found in chloroplasts, is used by plants to absorb solar light energy.

Carbon Dioxide (CO2): Via tiny pores on their leaves known as stomata, plants absorb carbon dioxide from the environment.

Chloroplasts: The collected light energy in the chloroplasts powers the production of glucose molecules from carbon dioxide and water.

Glucose Production: During the Calvin cycle, carbon dioxide and water molecules mix in the presence of light energy to create glucose (C6H12O6) and oxygen (O2).

HWE states that genotype and allele frequencies in a population remain constant from generation to generation when evolutionary influences are absent(such as gene flow or natural selection).

Final answer:

The frequency of alleles in a population that is in Hardy-Weinberg equilibrium remains the same over several generations as long as no evolutionary forces act on them. If frequency changes are observed, it indicates that the population may be evolving.

Explanation:

The Hardy-Weinberg principle outlines the conditions under which the frequency of alleles in a population remains constant over generations. This equilibrium assumes that no evolutionary forces are acting on the allele frequencies. The correct answer to the question is d. Remains the same over several generations. The principle hook on an ideal situation where there is no natural selection, no mutations, no gene flow, no genetic drift, and random mating occurs. If these conditions are met, the allele frequencies should remain unchanged from generation to generation, which implies that the population is not evolving. However, if observed allele frequencies deviate from expected values, scientists can infer that evolutionary forces are influencing the population.

The silkworm cannot survive there because of coldness. And the egg of Silkworm only hatches once it gets the temperature of 18°C to 25°C. So, it can be stored for the desired time below 18°c.

Eggs are stored for long periods of time in cold places to prevent larvae from hatching from eggs. During the larval stage of the silk moth's life cycle, silk threads are made. It takes 28-30 days to complete the larval stage.

Oocytes are stored in the ovarian follicle. During a woman's life, numerous follicles and eggs are mobilized to initiate the process of growth and maturation.

Farmers store their eggs in the hygienic and appropriate temperature and humidity conditions. Heat the eggs to the proper temperature to allow the larvae to hatch from the eggs. This happens when the Morus alba tree has fresh leaves.

Answer:

C. Thrombocytes

Explanation:

Thrombocytes are also known as platelets. When you get a cut and a blood vessel gets injured, the thrombocytes are triggered by the bleeding. So what they do is that they clump up together forming some sort of a plug on the damaged area to stop the bleeding. The name thrombocytes actually came from a Greek word which literally means "clot".

20%

Explanation:

Cycads were up to 20% of the global flora during the Triassic and Jurassic Periods.

The ice cube melted into water and mixed with the stew, and according to the law of conservation of mass, the mass of the ice cube was conserved and became part of the stew's liquid volume.

Based on the law of conservation of mass, when the little boy placed the ice cube in his hot bowl of stew and it disappeared, the ice cube actually underwent a physical change from solid to liquid due to the transfer of heat from the stew to the ice. This heat energy caused the ice to melt and mix with the stew, ensuring that the mass of the ice cube was conserved and became part of the stew's liquid volume.

The mass of the system (the stew and the ice cube together) remained the same throughout the process. Even though the ice cube appeared to have vanished, its mass was still present in the form of water mixed into the stew. Therefore, according to the law of conservation of mass, the total mass before and after the ice cube melted is the same, indicating the ice simply changed state from solid to liquid.

Answer:

D. Their energy output is in the form of direct current.

Explanation:

The inverter converts the DC to AC so that the appliances that use ac may function. They are mostly connected after the power storage appliances normally batteries before the consumption appliances. Inverters convert direct current electrical energy to alternating current at a given voltage and frequency.

Solar cells need an inverter to convert the direct current they produce into alternating current, which is used by household appliances and the power grid. the correct option is  D. Their energy output is direct current.

Solar cells generate electricity through the photovoltaic effect, converting sunlight directly into electrical energy. The energy produced by solar cells is in the form of direct current (DC). However, most household appliances and the electrical grid operate on alternating current (AC). This is why solar cells need an inverter: to convert the DC electricity they produce into AC electricity that can be used in the home or fed back into the power grid. The correct answer to why solar cells need an inverter is D. Their energy output is direct current.

A karyotype is the number and appearance of chromosomes in the nucleus of an eukaryotic cell. The term is also used for the complete set of chromosomes in a species or in an individual organism and for a test that detects this complement or measures the number.

What Is a Karyotype?

A karyotype is simply a picture of a person’s chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope. Then, the picture of the chromosomes is cut up and rearranged by the chromosome’s size. The chromosomes are lined up from largest to smallest. A trained cytogeneticist can look for missing or extra pieces of chromosome.

karyotype[1]There are 22 numbered pairs of chromosomes called autosomes.  The 23rd pair of chromosomes are the sex chromosomes.  They determine an individual’s sex.  Females have two X chromosomes, and males have an X and a Y chromosome.

How are the Chromosomes Numbered?

Each chromosome has been assigned a number based on its size. The largest chromosome is chromosome 1. Therefore chromosome 18 is one of the smallest chromosomes in humans.

Human karyotypes: 2n = 48 or 46?

   Early studies of the human karyotype simply stained chromosomes within cells with Giemsa and "squashed" them between the cover slip and slide. Most cells were not at the proper mitotic phase for chromosomes to be observed, and chromosome separation was poor. The exact count was uncertain: most workers accepted the number 48. The breakthrough came in 1952 (left) when a technician in the lab of T. C. Hsu accidentally substituted distilled water for the normal saline solution used in washing the cells just before "squashing". This "hypotonic" treatment caused the cell nuclei to swell, and allowed the chromosomes to separate before squashing. A further refinement was "dropping" the cells onto the slide at arm's length, which caused the nuclei to burst on impact, further separating them (middle slide). Finally, the use of a plant spindle-poison Colchicine allows chromosomes to be arrested at mitotic metaphase, during their maximum state of compaction [right] These experiments quickly established the human chromosome number as 2n = 46 chromosomes.  

   Classification of  chromosomes into seven groups by size and relative centromere position established the so-called "Denver System" (right) in 1960. Chromosomes within groups B - G were not readily distinguishable from each other. The X chromosome is in the C group, and the Y is in the G group: males are reconizable by five small G-type chromosomes. Modern banding techniques allow each chromosome in the karyotype to be distinguished individually.

They are the same genus but different species.

Explanation:

You can tell this because the first name (genus) is the same but the second is different.

They are the same genus but different species this because the first name (genus) is the same but the second is different.

The Binomial nomenclature has been known ask the method by which the naming of the organism is done. Each and every organism has been known by two names. One has been known as the local name and other is global name which is used by all.

The plants and animals has been named just according to the binomial nomenclature in which the first word of the name has been describes the genus of the organism and the second word would represents the species of the organism.

The individual having the name of the Pinus palustris and the Pinus elliottii belong to the same or the similar genus but the different species as their first name has been known as the same.

Therefore, They are the same genus but different species this because the first name (genus) is the same but the second is different.
