They do for the lodgepole tree population Seeds from cones on the forest floor may provide a viable seed bank for lodgepole pine regeneration following forest destruction by mountain pine beetles.

What is a possible limiting factor of that lodgepole pine?

The mountain pine beetle is the limiting factor to the population of lodgepole pines in Colorado. It devastated large numbers of trees in the state and in the northern mountains of the United States.  

Thus, lodgepole pine regeneration follows forest destruction by mountain pine beetles.

help me ..it's a MCQ

Answers

Explanation:

I think your answer is D, and let me explain why.

Heat can denature proteins quickly because proteins have very specific temperatures at which they act best. If the temperature rises too high/falls too low with respect to that threshold, then that will cause the proteins to stop working properly and eventually die.

pH is also very important with how proteins work, and it's the same reason as heat. Proteins have a certain range of pH's that keep them healthy and working, but as soon as the pH changes dramatically outside of that range, the proteins will be quickly denatured.

And lastly, organic solvents can denature proteins as well (e.g. alcohol), which makes sense because they are solvents (a solvent is something that dissolves other substances). I'm not sure about the exact chemistry / biological responses behind it, but it's what would be expected of a solvent.

With all of this in mind, I think your answer should be D!

How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the heart

Answers

Answer:

two capillary beds

Explanation:

Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.

Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change

Answers

The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.

What is the role of the leaves?

Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.

Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.

Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

Answers

The U.S. central plains region -- nicknamed Tornado Alley -- suffers the highest frequency of tornadoes in the world [source: Tarbuck]. Many of these twisters leave death, injury and destruction in their wake, but one stands in a class by itself.

Sweeping out from southeastern Missouri on March 18, 1925, the Tri-State Tornado careened across the southern tip of Illinois before dissipating in lower Indiana. Remarkably, these three locales lie 219 miles (352 kilometers) apart, and the tornado traveled this distance in just three and a half hours [source: SEMP].
With up to 155-mph winds, Hurricane Iota smashed record books on Nov. 16 as the strongest hurricane ever recorded to make landfall in Nicaragua. Iota reached Category 5 strength before making landfall as a Category 4 storm near the town of Haulover, Nicaragua.

The onslaught of destructive winds and heavy rainfall was unfortunately familiar to a region that recently suffered another Category 4 landfalling storm – Hurricane Eta – just two weeks earlier. Eta was a Category 4 storm with 140-mph winds when it landed in Nicaragua on Nov. 3 before ripping a wide path of destruction through Honduras and Guatemala.

Heavy rainfall from these two storm systems brought widespread flooding to the region, triggered large and numerous landslides in Guatemala and Honduras, and was responsible for numerous casualties.

NASA’s Earth Applied Sciences Disasters Program supports disaster response and risk reduction efforts throughout the world — before, during, and after disasters strike – and is working to aid Central America with the impacts from these storms.

In the case of Eta and Iota, the Program is using imagery and data from Earth-observing satellites to provide scientific analysis to Guatemala’s National Coordinator for Disaster Reduction and is working with the Coordination Center for Disaster Prevention in Central America. The multi-agency collaboration is assisting local governments in Nicaragua, Honduras and Guatemala, El Salvador, Belize, Costa Rica, and Panama. The Program is also working with U.S. Southern Command to provide situational awareness for potential emergency humanitarian assistance.

Organisms use glucose to store and transport energy.
True
False

Answers

Answer:

Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.

Explanation:

Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.

What do organisms use to store and transport energy?

All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.

Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.
