how scientists are able to determine climate information by just looking at tree rings? (how does it work?)
Explanation:
Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry.
Answer:
Explanation:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.

What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group
Complete question:
Question 49 (1 point) The following questions refer to the description below. You have read that soapberry bugs, Jadera haematoloma, adapt to available food sources. For example, in southern Florida, soapberry bugs feed on seeds of a native plant, the balloon vine. In central Florida, the balloon vine is rare and soapberry bugs have switched to eating seeds of an introduced species, the golden rain tree. The seeds of the golden rain tree fruits are much closer to the fruit surface than the seeds of the native balloon vine fruit. As a result, natural selection results in beaks that are shorter in soapberry bugs that utilize golden rain tree fruits than those that feed on balloon vine fruit seeds.
What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group?

What is the mechanism by which binding of testosterone to the testosterone receptor leads to upregulated gene transcription
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.

precipitation
A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers
Answer:
B) Trees at high elevations
Explanation:
The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.

Only a very few flowering plants have been able to invade the oceans. But the few marine ones are very successful. What are some reasons for the small number of marine flowering plants
Answer:
1. High osmotic pressure due to the hypersaline nature of marine habitats
2. The dependence of flowering plants on pollinating insects for fertilization. These insect pollinators are however, absent in the marine environment.
3. Competition from already-established sea weeds and grasses provides another challenge to flowering plants invadingnthe oceans.
4. Constant changes in the environment as well as temperature changes too
Explanation:
The marine environment is a hypersaline environment with a high salt concentration relative to that of the plant cell. Due to high salt concentration of the marine environment, their is high osmotic pressure on living oragnisms found therein. Organisms must have well-adapted osmo-regulatory mechanisms to counteract the high osmotic pressure of their environment. Therefore, flowering plants face the challenge of removing excess salt from their cells or else lose water to their environment, hence resulting in the death of the plant. However, most flowering plants lack this ability and thus, have found it difficult to invade the oceans.
Flowering plants depends on insect-pollinators for fertilization. However, these insect are not found in the oceans, and as such, it is difficult for flowering plants to invade the oceans.
Well-adapted seaweeds and grasses serve as competitors for any invading flowering plant. Since the flowering plants are not yet adapted for life in marine habitats, they lose out in this competition.
The oceans are constantly in a state of frequent turbulence and change due to tides and currents. Also, the temperature of the oceans are very low and fluctuations in the temperatures of the ocean do occur, utimately serving as obstacles to invading flowering plants to adapt to life in the oceans and seas.

• Write the biofuel and biogas chemical formulas. Explain why biofuel and biogas are still considered energy-dense molecules. Compare the chemical makeup of each component to carbon dioxide, which is produced when glucose is completely oxidised.
Answer:
diesel fuel is C12H23 whereas Methane is CH4.
Explanation:
The chemical formula for common diesel fuel is C12H23 while o the other hand, the formal of biogas such as Methane which is CH4. Both are organic compounds due to the presence of hydrogen and carbon. Biofuel and biogas are still considered energy-dense molecules because they have more mass and produced large amount of energy from it. The main difference between Carbondioxide gas and biofuel is that there is no hydrogen present in the formula of carbondioxide gas.
Why are there two versions of chromosomes
Answer:
See below
Explanation:
There are two different types of chromosomes coming from the ribosomes of a single cell. This is simply because you inherit traits from both your mother and father when you are given birth to. So, there are two types of genes which do not pair and therefore form two types of chromosomes.

This apparatus can be used to show osmosis.
(a) Explain what happens to the level of sucrose solution in the glass tube. [3]
(b) Describe how this apparatus could be modified to measure the rate of osmosis at different temperatures. [3]
Answer:
A. The level of sucrose solution will rise in the glass tube because water molecules will pass through the semipermeable membrane into the tube as water potential is higher outside than inside the tube.
B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :
1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.
2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.
3. Using a stopwatch to record time taken for unit increase in the height of waterat different temperatures.
Explanation:
A. Osmosis is the movement of water molecules from a region of low solute concentration or high water potential to a region of high solute concentration or low water potential through a semipermeable membrane until equilibrium concentration is attained.
The movement of water molecules is based on a concentration gradient, from a region where there are more water molecules to a region where there are fewer water molecules.
The sucrose solution has a higher solute concentation but lower water potential due to fewer water molecules compared to water in the beaker, therefore, water molecules will pass through the semipermeable membrane into the glass tube resulting in an increase in the level of sucrose solution in the glass tube.
B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :
1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.
2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.
