Describe how the lizard population is changing
Answer:
Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.
a fossil find contains impressions of leaves that lived on the ancient plants. How would you classify this type of fossil?
A.) original material
B.) molds and casts
C.)amber
D.) replacment
Answer:
molds and casts
Explanation:
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains. This is called a cast.

What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes.
Hence, DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.

what is photosynthesis
Answer:
please tell me you know, my hands are literally shaking at how easy this question is
Explanation:
the answer is photosynthesis is a way for plants to make oxygen
still not enough information? they convert carbon-dioxide and water into oxygen and sugar, so they eat the sugar making their own food, put plants are living if they eat sugar. so they also have cellular respiration from mitochindria (photosynthesis is from chloroplasts and chrolophyll inside the chloroplast) and plants BREATH OUT SOME CARBON-DIOXIDE and produce more Oxygen than carbon-dioxide, thus providing the earth with Oxygen
What are the raw materials (reactants/goes into) for photosynthesis?
A. water and glucose
B. carbon dioxide and water
C. glucose and oxygen

Explain how specialized structures found in multiflora rose support its reproduction and spreading/dispersal throughout ecosystems in the United States. Use evidence and scientific reasoning to support your response.
Answer:
Presence of thorn stems, invasive nature and strong scent of of multi rose plant.
Explanation:
The presence of thorn stems, invasive nature and strong scent of of multi rose plant are the specialized structures found in multiflora rose support its reproduction and spreading and dispersal throughout ecosystems in the United States. The presence of thorn stems prevent animals to feed on the multi rose plant while on the other hand, strong scent of of multi rose flower attract pollinators that increase its pollination and increase occur in its population.

When a piece of paper or wood is burned, you are left with ashes that seem to weigh less than the paper or wood before it was burned. Yet when a substance is burned, it is oxidized and therefore must weigh more than it did before it was burned. Explain what happened to the “missing” weight.
It just got blowed or you can say get mixed in the air around you. You can see tiny pieces of ash while buring paper or wood. And that's exactly your answer.
Answer:
The ashes of the wood or paper either got blown around in the wind because of the ashes being so small and weightless, or they went into the air around you.
Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

Answer:
Antigens are secreted by the endocrine system
Explanation:
The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with
Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.
What happens to cause air to be exhaled from the lungs?
A)The rib muscles contract and move upward
B)The chest cavity expands and grows larger
C)The diaphragm relaxes and moves upward
D)The lungs contract and expand
Answer:
The answer is C.
Explanation:
When you breathe out or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.
