Choose the statement below that is true. Photosynthetic enzymes are denatured at high temperatures. Increasing temperature always increases the rate of photosynthesis. Too much carbon dioxide is toxic for plants. The main limiting factors are temperature, light intensity and oxygen concentration.
Answer:
The correct answer would be -
Photosynthetic enzymes are denatured at high temperatures
Too much carbon dioxide is toxic for plants
Explanation:
Temperature is a limiting factor for the rate of photosynthesis due to the fact the at high-temperature photosynthesis is affected as initially with an increase in temperature rate of photosynthesis but after a limit, it becomes constant and increasing above that will result in denaturing of the photosynthetic enzymes.
CO2 is also a limiting factor that limits the photosynthetic rate if too little or affects the photosynthesis in the too much amount by denying the O2 intake by soil and make leaves thick.
Fossils are preserved remains of previously living organisms or the traces dating from the distant past fossils that have been collected offer unique insight into evolution offer a long time scale however fossils have some limitations select all the limitations of using fossils as evolution evidence
Answer: There are 3 answers.
1- Plate tectonics causes loss or displacement of fossils.
2- Most organisms never fossilize, leaving holes in the fossil record
3- Because marine fossils are prevalent, this can lead people to believe they were more dominant than they actually were.

9) How do the shapes of our ears help us to hear?
1.The ridges in the ear help us capture sound
2.Our ears are large allowing them to pick up quieter sounds
3.Our ears are shaped like a funnel, allowing sound to be funneled into our ear canal
4.Our ears are placed on the side of our head to maximize the sounds we car hear
The shapes of our ears help us to hear by the fact that they are shaped like a funnel that allows the sound to be funneled into our ear canal. Thus, the correct option for this question is C.
What are the major parts of the ear involved in the hearing process?The major parts of the ear that are involved in the hearing process are the auricle (pinna), ear canal, ear drum or tympanic membrane, cochlea, etc.
The auricle is the outermost part of the ear that is visible. It significantly gathers the sound waves from the surroundings and directs them to the ear canal. In this region, the sound is amplified. The amplified sound waves then travel to the end of the ear canal known as the tympanic membrane.
The vibration then migrates through the fluid in the spiral-shaped inner ear known as the cochlea. This region is surrounded by hair cells that detect the motion and transform it into chemical signals for the hearing nerve.
Therefore, our ears are shaped like a funnel, and allowing sound to be funneled into our ear canal is a statement that best describes the process. Thus, the correct option for this question is C.

What is a kingdom?In biological classification, a kingdom is the second highest taxonomic rank below domain. It is used to group organisms based on their similarities and differences in characteristics and traits. The system of classification, known as Linnaean taxonomy, categorizes living things into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
Each kingdom is defined by specific characteristics such as cell structure, mode of nutrition, and reproductive strategies. For example, the Monera kingdom consists of unicellular organisms with prokaryotic cells, while the Plantae kingdom includes multicellular organisms that produce their own food through photosynthesis.
The kingdom level of classification helps scientists understand the relationships and diversity of living organisms, which is important for fields such as ecology, evolutionary biology, and biotechnology.

Which taxon includes the most specific characteristics?
Answer:
Species taxon includes the most specific characteristics.
I hope this might be the answer for ur question ☺️
The most specific characteristics are seen in Species Taxon.
What is Taxon?Taxon is defined as the unit of taxonomy which are arranged in a hierarchy from kingdom to species.
The taxonomic classification was given by Carlos Linnaeus who is known as the Father of Taxonomy.
In descending order it is classified as:
Kingdom - Phylum - Class - Order - Family - Genus - Species
A taxon is usually known by a particular name and given a particular ranking and is given formal science name, its use is then governed by one of the nomenclature code specifying which scientific name is correct for particular grouping.
What is species?Species are the most specific taxon which share common traits and characteristics closely to each other and are capable of interbreeding.
It is the largest group of organisms in which any two individuals of the appropriate sexes or mating type can produce fertile offspring through sexual reproduction.
Types of species:
- Typological/ Morphological Species:
Individuals are having fixed properties as can be easily recognized by the modern taxonomist.
- Recognition/ Cohesion species:
Group of sexually reproducing organisms recognizing one another as potential mates.
- Genetically similar
- Phylogenetic/ Cladistics species:
These are the smallest group based on unique combination of character states in comparable individuals.
- Evolutionary species:
Set of species adapted to a particular set of resources called niche in the environment.
- Genetic Species:
Set of genetically isolated interbreeding populations.

All nucleotides of DNA and RNA contain a
a) uracil base
b) thymine base
c) ribose sugar
d) phosphate group
Answer:
Phosphate group
Explanation:
Each nucleotide consists of a heterocyclic base linked via a five-carbon sugar (deoxyribose or ribose) to a phosphate group. DNA and RNA each contain four different bases. The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA. So both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.
All nucleotides of DNA and RNA contain a phosphate group. Hence, option D is correct.
What do you mean by Nucleotides?Nucleotides may be defined as the components of nucleic acids. It is composed of a phosphate group, a nitrogenous base, and sugar.
Uracil base is present in RNA, thymine base is present in DNA, ribose sugar is found in RNA, while deoxyribose sugar is found in the DNA.
Therefore, all nucleotides of DNA and RNA contain a phosphate group.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?
A. There are variations in their RNA sequences.
B. The leaves and flowers show morphological differences.
C.They produce viable but sterile offspring.
D.They occupy unique habitats in an ecosystem. .
Answer:
the answer is C
Explanation:
Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.
The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.The biological concept of species states that mating between individuals of the same species produces viable offspring.The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
