Why do some scientists believe that dinosaurs were warm blooded?
Answer:
Some paleontologists think that all dinosaurs were 'warm-blooded' in the same sense that modern birds and mammals are: that is, they had rapid metabolic rates. ... Some scientists think that very big dinosaurs could have had warm bodies because of their large body size, just as some sea turtles do today.
Explanation:
Hope this will help you
Some scientists believe that dinosaurs were warm-blooded because of evidence from their fossilized bones, growth rates, and the presence of features similar to modern warm-blooded animals.
The belief that dinosaurs were warm-blooded is based on several lines of evidence. First, studies of fossilized dinosaur bones have revealed features such as Haversian canals, which are characteristic of fast-growing, metabolically active animals. This suggests that dinosaurs had high metabolic rates similar to warm-blooded animals.
Second, researchers have analyzed the growth patterns in dinosaur bones and found that they exhibit characteristics of rapid growth, which is consistent with the growth rates observed in warm-blooded animals. Slow-growing reptiles, on the other hand, show different growth patterns.
Furthermore, some dinosaurs show evidence of insulation in the form of feathers or other types of integumentary structures. These structures would have provided insulation and helped regulate body temperature, similar to how feathers function in modern warm-blooded birds.
Additionally, the presence of large predators among the dinosaur species suggests an active and energetic lifestyle that is more characteristic of warm-blooded animals than cold-blooded reptiles.
While these pieces of evidence suggest that dinosaurs were warm-blooded, it is important to note that the debate among scientists is ongoing, and there is still no consensus. The study of dinosaur physiology is challenging due to the limited information available from fossil remains. Nonetheless, these lines of evidence contribute to the hypothesis that some dinosaurs may have exhibited warm-blooded characteristics.

Answer:
radiation = transfer of energy from the Sun
infrared radiation = takes the form of heat
ultraviolet radiation = causes skin cancer and sunburn
electromagnetic wave = how Sun's energy travels to Earth
visible light = made of colors that the eye can see
Explanation:
Radiation is the transmission of energy in the form of waves or particles through space or a vacuum or through a material medium. The energy produced by the sun is transferred to other bodies such as the earth through radiation.
Infrared radiation is a form of electromagnetic radiation that is invisible to the human eyes but that takes the form of heat energy.
Ultraviolet radiation is an invisible form of electromagnetic radiation. It is produced by the sun and overexposure to it can cause sunburns, skin cancer and possibly blindness.
Electromagnetic waves are waves that are produced as a result of vibrations between an electric field and a magnetic field. The energy from the sun travels in the form of electromagnetic waves.
Visible light is a form of electromagnetic wave produced by the sun as well, that makes up the visible colors that we can see such as red, blue, green, etc.

What features evolved over time in the different animal phyla and classes? How did the features provide advantages that helped each group survive in their environment?
Answer:
What features evolved over time in the different animal phyla ? 5 Animals That Have Evolved Rapidly
Guppies Adapted to Predators. ...
Green Anole Lizards Adapted to an Invasive Species. ...
Salmon Adapted to Human Interference. ...
Bedbugs Adapted to Pesticides. ...
Owls Adapted to Warmer Winters.
How did the features provide advantages that helped each group survive in their environment?
Examples of the basic adaptations that help creatures survive:
shape of a bird's beak,
the number of fingers,
colour of the fur,
the thickness or thinness of the fur,
the shape of the nose or ears.
it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease or change in environment is less likely to affect all the individuals in a population.
Animals develop a certain feature in their body, which denotes the natural selection condition which helps them for survivorship. For, example bedbugs adapted to pesticides
How evolution in animal phyla and classes helps with adaptation?There are several features developed in the animal phyla, which make the animals adapt to their changing environment over time.
Guppies adapted to predators, if any organism adapted to its predators, it can increase the population of that organism. The shape of the bird's beak helps them to catch the food which is necessary for its survival in that environment.
Therefore, this condition tells about natural selection, for the better survival of the organism, it may occur to change their body conditions and their behavior to adapt to that conditions.

All of the offspring produced in a test cross involving a brown rabbit and a white rabbit are brown. The result of this cross is best explained by A. Incomplete dominance B. Codominance C. Crossing over D. Dominance
Answer:
D
Explanation:
The result of the cross is best explained by dominance.
According to Mendel, when the alleles that make up a gene are different and one of the alleles is dominant over the other, the dominant allele would mask the effects of the recessive allele.
In the same vein, when the alternate version of the same trait is dominant, such trait would be expressed over the other version in heterozygous state.
Assuming that the genotype of the brown rabbit is BB and that of the white is bb. When the two rabbits are crossed:
BB x bb
Bb Bb Bb Bb
All the offspring would be heterozygous and brown in color because the brown allele is dominant over the white allele.
Hence, the correct option is D.

Answer:
Oxaloacetate (4 carbon) joins with Acetyl CoA to yield Citrate (6 carbon)
Explanation:
Citrate synthase is an enzyme required during the first step of the citric acid cycle. This enzyme catalyzes the condensation of Acetate from Acetyl Coenzyme A (Acetyl CoA) and Oxaloacetate to yield Citrate, a six-carbon molecule, and Coenzyme A (CoA). Oxaloacetate is first condensed with acetyl CoA to produce citryl CoA which is subsequently hydrolyzed to CoA and citrate.
