The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
Morphological evidence: Physical structures and traits indicate evolutionary relationships.
Biochemical evidence: Genetic and molecular similarities indicate evolutionary relationships.
Evolution is supported by morphological evidence. Scientists can establish evolutionary links by analysing species' anatomy. Homologous structures, which have a common origin but diverse functions, reflect a shared lineage. Comparative examinations of bone structure, limb arrangement, or body plans can reveal evolutionary links.
Biochemical data emphasises genetic and molecular similarities between organisms. Scientists may compare DNA, protein, and other substances at the molecular level. Common ancestry and evolution explain these commonalities. Comparing genetic sequences can show how closely related species are and when they evolved from a common ancestor.

enzymes that cleave nucleotides from the ends of a dna molecule are known as what?
Enzymes that cleave nucleotides from the ends of a DNA molecule are known as Restriction endonucleases.
What are Enzymes?Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.
Restriction endonucleases are the enzymes that are also called molecular scissors which are responsible for cutting DNA at specific sites. These enzymes are present in bacteria in order to provide a defense mechanism called the restriction modification system.
There are various types of restriction enzymes are known. For example, BamH1, EcoRI, Hind III, etc.
Therefore, restriction endonucleases are the enzymes that cleave nucleotides from the ends of a DNA molecule.

how will climate change affect the habitat distribution for the baltimore oriole?
Climate change has a great effect on the habitat distribution of Baltimore orioles bird.
Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.
The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

In sexual reproduction, will an offspring show a recessive trait if just one of its parents has recessive alleles for that trait? Explain your answer.
Answer:
No, they will not
Explanation:
In this question, we assume that the parents have genotypes of rr and RR (I use "r" out of convenience). If we cross both of these parents, it is impossible for any of the offspring to be rr like the one parent. They would all be heterozygous. If the other parent had a single recessive allele, then it would be possible.

Which organism carries out autotrophic nutrition
Answer:
Autotrophs is the answer
Example : plants
Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.
Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.
Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

at the most basic level, schizophrenia is best conceptualized as a/an ____________ disorder.
At the most basic level, schizophrenia is best conceptualized as a neurodevelopmental disorder.
It is characterized by a complex interplay of genetic, environmental, and neurobiological factors that disrupt brain development and function during early stages of life.
While the exact causes are not fully understood, research suggests that abnormalities in brain structure, neurotransmitter imbalances, and genetic predisposition contribute to the onset of schizophrenia.
These disruptions may affect cognitive processes, emotional regulation, and perception, leading to symptoms like delusions, hallucinations, disorganized thinking, and social withdrawal.
Understanding schizophrenia as a neurodevelopmental disorder highlights the importance of early detection, intervention, and holistic treatment approaches to improve outcomes and quality of life for individuals affected by this condition.

How do human beings affect the carbon dioxide and oxygen cycle?
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.
Answer:
By breathing.
Explanation:
Humans inhale oxygen, and when they need to release it, (exhale) that oxygen is no longer oxygen and is now carbon dioxide. Trees and plants are what helps oxygen to exist in our world even though we breathe it in and convert it to carbon dioxide. Hope this helps ^^

H-E-L-P! ASAP! Describe two ways that plants respond to their environment, giving an example of each. Your answer can include ways that plants respond to seasonal changes, light, gravity, or touch.
Plants have evolved to respond to critical changes in the environment by either growing their roots, or leaves towards/away from any stimulus. This response, is called a tropism.
For example, The plant's stem and leaves bend toward sunlight. Their roots grow toward Earth's gravity.
Plants have complicated systems to detect and then respond to changes in light, gravity, temperature, and or even physical touch.
