Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals-such as woolly mammoths and saber-toothed tigers-are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles' climate history by studying the specimens found in these tar pits?
More than one million bones were recovered in 1906. These bones represented 231 species of vertebrates and there were 234 species of invertebrates.
Los Angeles climate is relatively stable for over 50,000 years. The fossils of more than 180 insects were preserved in La Brea Tar Pits. The climate warming probes a link for evolution of Ice Age predators.

Answer:
scientists at the tar pits discovered that many of the smaller animals they extracted from the pis still exist around los angeles today. But many of the larger mammals such as wooly mammoths and saber toothed tigers are now extinct. I believe this is the case because since bigger beasts couldnt take shelter in small protected burrows, perhaps they were done in by fierce environmental conditons. Or maybe with so many plants dying off, big herbivores simply had nothing to eat, and as they died out, so did the big carnivores.La brea tar pits are probing the link between climate warming and the evolution of ice age predators, attempting to predict how animals will respond to climate change today.

11) base pairs
12) G with C and A with T
13) 1953
14) died
15) unwound
16) synthesized; a new molecule
Explanation:
Nitrogenous bases are used to construct nucleotides. Until the discovery of the helical shape of the DNA molecule, were only possible to identify the genetic material (chromosomes) by the microscope. Chromosomes are composed of DNA and proteins (histones). Nucleotides are the building blocks of the DNA molecule. The X-ray diffraction data obtained by Rosalind Franklin were used to decipher the DNA structure. The ball-and-stick is a molecular model where atoms are represented by spheres and bonds are represented by rods. Chargaff's rules indicate that the content of cytosine is equal to guanine and adenine is equal to thymine. Rosalind Franklin died of ovarian cancer in 1958. The double-stranded DNA molecule must be unwound and then the DNA strands serve as templates to synthesize identical DNA molecules.

Antibodies are immunoglobulin produced in the body by B cells to help i
For immune response or fight against any foreign invade in the body.
There are two common classification of antibodies and these are;
1. Monoclonal antibodies are produced in the laboratory that can help to restore and improve the immune system against cancer attack.
They bind to the antigens and are many on the surface of cancerous cells than normal cells. They are use for medical research.
2. POLYCLONAL ANTIBODIES are produced by different B cells the body. They are produced from heterogeneous molecules in live animals. They can bind to numerous antigens. They are part of the natural immune response of the animals. They are produced by injecting the animal with immunogen.
Therefore, Polyclonal antibodies are part of the natural immune response; monoclonal antibodies are clones of plasma cells used for medical research.

The ovals above represent mangrove islands of various sizes and distances from shore. According to the MacArthur/Wilson Island Biogeography Model, which island is expected to have the LOWEST number of insect species at equilibrium
There are few island on earth which are insect free due to atmosphere and sea breeze which do not complements the insects breed.
These islands attract tourists more because of no or very few insects, tourist have no fear of getting sick during their stay on these islands.
Antarctica is mosquito free continent. The island in Antarctic ocean are mosquito and have very few insects due to lack of stagnant water available for their breeding.
Iceland, Seychelles and few other island are insect free or have very low amount of insects there. The coral island is all surrounded by water and there is no connection of this island with the land.
There is very less stagnant water and ponds which can cause the insects to survive.

Answer:
They are called promoter and regulatory genes.
Explanation:
There are different genes responsible for regulating transcription:
These are the inhibitors, promoters and regulators.
Regulatory genes are in charge of regulating that promoter or inhibitor genes remain intact or do not present mutations.
Promoter genes promote cell replication, hence transcription.
In the case of malignant or benign neoplasms, there must be yes or if the affection of a regulatory gene plus the affection of an inhibitory or promoter gene.

Lichens can best be described by which of the following? a) autotrophic organisms and fungi in a mutualistic relationship b) photosynthesizing fungi that can live in harsh environment conditions c) saprophytic fungi that secretes acids to grow on and colonize rocks d) two heterotrophic fungi species that thrive on nutrients from the air
Answer:
a) autotrophic organisms and fungi in a mutualistic relationship
Explanation:
A lichen "is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species".
It is cyanobacteria + fungi, so it has to be two separate groups, and both cannot be fungi.
Your question has been heard loud and clear.
answer is option C , lichens do colonize on rocks most of the time , this is because they really are saprophytic fungi , that secrete acids to melt and make the rocks suitable for growing on.

A country's ecological footprint can be calculated by multiplying its population size by the footprint of each individual. Why are some ecologists concerned about the ecological footprint of a country like India
Answer:
Ecological footprint estimates the requirements of renewable resources that a population consumes to live a particular lifestyle. Some ecologists are concerned because the result of the ecological footprint shows that the demand of the population is increasing in comparison to the supply of nature.
For example in India, the ecological footprint shows negative impact of population demand over supply of nature.
A projectile is fired vertically upward at an initial velocity of 100 m/s. How high will it rise? How long will it take to reach that height?
The question is solved using the equations of motion
According to the equations of motion:
[tex]v^2 = u^2 -2gh[/tex]
v = final velocity
u = initial velocity
g = acceleration due to gravity
h = height
Note that at the maximum height, the final velocity (v) = 0 m/s
so we can write:
[tex]u^2 = 2gh[/tex]
[tex]h = \frac{u^2}{2gh}[/tex][tex]h= \frac{100^2}{2 * 10}[/tex]
h = 500 m
The time taken is obtained from:
[tex]v= u - gt[/tex]
since v= 0 at maximum height
[tex]u = gt\\\\t= u/g\\\\t= 100/10\\t = 10 s[/tex]

The cell cycle occurs in which order?
A. G1, S, G2, Cytokinesis, Mitosis
B. G1, S, G2, Mitosis, Cytokinesis
C. S, G1, Mitosis, G2, Cytokinesis
D. S, G1, G2, Mitosis, Cytokinesis
Answer:
B. G1, S, G2, Mitosis, Cytokinesis
Explanation:
G1 is the first stage of the cell cycle, and it is essential for cell growth.
Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.
G2 is the next phase, and it involves preparing and growing the cell for mitosis.
Mitosis is the next stage, where the cell divides into 2.
Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.
So, the correct answer is B. G1, S, G2, Mitosis, Cytokinesis
Trees grow more quickly in the ________ than the ________, and the tree rings show up as ________ colored bands.
summer, winter, darker
summer, winter, lighter
winter, summer, lighter
winter, summer, darker
Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
