Answer:

Osteoid

Explanation:

The earliest form of spongy bone in a developing long bone is termed​ as Osteoid.

Osteoid is defined as the the unmineralized,  matrix material that is made up of a fibrous protein, collagen, and mucopolysaccharide and forms prior to the maturation of bone tissue.

Osteoblasts, the process of formation of bones takes place when inorganic salts starts depositing over osteoid to form the hardened material.

Hence, the correct answer is "Osteoid".

Answer:

I think it's D

Explanation:

I found this as its definition "any of the minute tubes which form a network in bone and contain blood vessels."

I’m assuming that this isn’t a true or false question. If so it’s true.

In prokaryotes, transcription and translation can happen simultaneously because DNA and ribosomes are both located in the nucleus. Therefore, option B is correct.

The ribosomes are responsible for protein synthesis. They are also found in the cytoplasm of prokaryotic cells. The ribosomes read the mRNA produced during transcription and directly synthesize proteins using the information encoded in the mRNA.

The absence of a nuclear membrane in prokaryotes allows for the coupling of transcription and translation to occur in close proximity in the cytoplasm.

Explanation:

When there is high selective pressure is the major factor in evolution.

Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.

Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.

The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.

Therefore, When there is high selective pressure is the major factor in evolution.

Answer:

Option B - because bee act as a medium for the plant for fertilisation due to which plant reproduce but if the population of bee decrease this will affect the rate of reproduction in plants.

The population of this particular type of plant be affected if the bee population decreased dramatically because the plant would not reproduce as effectively, and the plant population would decrease. Thus, the correct option is B.

A Population may be defined as the group of individuals belonging to the same species living in the same area at a given time. This represents the members of the same species in a definite area.

The population of bees is significantly necessary for mediating the process of pollination that involves the mechanism of sexual reproduction in plants.

But if the population of bees is reduced due to any factor, this plant does not undergo the process of pollination which ultimately leads to the reduction in the population of this plant as well.

Therefore, the correct option for this question is B.

Answer:

2. Mineral composition

Explanation:

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Minerals is any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Hence, mineral composition is the main factor that causes bedrock to weather at different rates.

Answer:

Chemical weathering erodes the land/basically sort of melts the land away due to the pollution in the rain.

Explanation:

Answer:

Chemical weathering changes the molecular structure of rocks and soil. ... Sometimes, chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst. In these areas, the surface rock is pockmarked with holes, sinkholes, and caves.

Complete question:

A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall. After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure. Complete the following statements about the two bat species.

a. fundamental niche

b. realized niche

c. character displacement

d. intraspecific competition

e. interspecific competition

f. (-\-)

g. resource partitioning

h. competitive exclusion

Answer:

Explanation:

A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.  

In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.

2) a. lysine and arginine

3) g. two

4) d. four

Explanation:

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.

Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.

1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.  

2. Localization:

Transcription: within the cell nucleus (in eukaryotic organisms)

Translation: cytoplasm

3. Enzymes :

Transcription: RNA polymerase

Translation: Peptidyl transferase

Explanation:

Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.

Explanation:

Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.
