Answer:
Iguanas
Explanation:
Dinosaurs used to be depicted as slow, unintelligent, lizard like animals. Iguanas fit that mold perfectly. Now we know they acted more like birds than lizards (Theropod dinosaurs anyway)

An experimenter wants to know which type of light bulb promotes the most plant growth. He plants 50 pea plants in a room under GE brand light bulbs and another 50 pea plants under Phillips brand light bulbs. Water, temperature, soil type, and other conditions are kept the same between both groups of plants. He allows both groups of plants to grow for 30 days and records the growth of each plant twice daily.
The rate at which the plants grow is the ____
Answer:
i Did this the rate at which it grows is 50 peas ÷ 50 peas × the x which is 11x × 3yi so then it is 33

Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse then receive a responding pulse from the heart
True or False?
Answer:
true
Explanation:
i looked in my book for this
Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.
What is the heart's electrical signal?The heart has the SA node that autonomously originates the signal, and then the AV nodes receive that, and then the signals are transmitted to the ventricle and the heart contracts. In this process, the heart's electrical signal travels through the atrium and ventricle, and when the device measures the signal, the tiny electrical pulse is received by the device, which shows the electrical nature of the heart.
Hence, electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.

20. What is the best explanation for why the change in temperature is
different for the each of the colored boxes? *
Answer:
Dark surfaces become warmer because they absorb more of the incident radiation. Light-colored surfaces reflect more of the incident radiation, hence absorb- ing less radiation. The higher the absorption, the warmer the temperature.

This person has children with a partner that does not have hemophilia. Is it possible for any of their children to have hemophilia?
Answer:
A family may have children with the hemophilia gene and children without it. It is also possible for all the children in the family to inherit the normal gene or all to inherit the hemophilia gene.
Explanation:
How much carbon-14 remains at the end of five half-lives? Explain your
reasoning.
Answer:
1/32 of the original amount.
Explanation:
Each half-life is half of the prior life so:
1st half-life = 1/2
2nd half-life = 1/4
3rd half-life = 1/8
4th half-life = 1/16
5th half-life = 1/32
Answer: 1/32
Explanation: because you ask how much carbon-14 remains at the end of five half-lives! and you told me Explain my reasoning. your welcome
can anyone help me on this question ?

how did eukaryotic cells evolve prokaryotic cells?
Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes (endosymbiosis) is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
Explanation:
Both mitochondria and chloroplasts are similar to bacteria in size, and like bacteria, they reproduce by dividing in two.
Why is it important that the DNA is replicated during the S phase of interphase
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

Answer:
Proteins
Explanation:
These are all examples of proteins
As a protein, insulin is made up of two chains A and B each of these chains have 21 and 30 amino acids.
As a protein, haemoglobin has 4npolypeptides chains. Each of these chains have greater than 140 amino acids. The chains are attached to a heme group.
Albumin is also a protein. It's composition is about 69% of blood protein. It is made by the liver.
Maltose is a disaccharide
The school district wanted to determine whether the more expensive floor wax (Brand A) was better than the cheaper (Brand X) floor wax at protecting its floor against scratches. One liter of each brand of floor wax was applied to each of 10 test sections of the cafeteria floor. The test sections were all the same size. Ten other test sections received no wax. After 4 weeks the number of scratches in each of the test sections were counted.

Explanation:
.The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.

Why does the moon have a effect on the sea?
will give BRAINLIEST and a thank you!
Answer:
The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. ... High tides and low tides are caused by the Moon give me brainliest
