Answer:

In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.

Name two conditions that must be met for a reliable Gram staining result.
Hatshy [7]

Answer:

The two important conditions that must be met before gram staining are-

1. The age of the culture should not exceed 24 hours.

2. Over heating, decolonization should be avoided.

Explanation:

Gram staining is a technique developed to distinguish the bacteria on the basis of the composition of the cell wall around the bacteria.

The gram stain is a sensitive technique so must be performed carefully.  The precautions should be taken to avoid any error while gram staining that is-

1. Age of the culture- The culture should be freshly prepared just 18-24 hours before the experiment as above 24 hours bacteria lose their ability to retain the color so one would not be able to differentiate between the cultures.

2. While performing the experiment one should avoid overheating and decolorization with ethanol as both the factors lead to the loss of crystal violet stain from the cell and they take pinkish color after safranin staying.

How do dung beetles help a carbon atom in animal dung to become part of a carbohydrate molecule within a plant?
Ber [7]

Answer:

Dung beetles lives in the animal dung and take nutrients from the undigested substances present in the dung. This dung is mixed with the soil by the beetle to increase the fertility of the soil. These nutrients is taken by plants with water through roots and makes their food in the form of carbohydrate from it in the process of photosynthesis. This carbohydrate is stored in different parts of plant body.

A musk ox and the Alstroemeria flower have physical structures and organs that have similar functions. Provide two examples of s
gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.

We gain energy from eating plants. Plants create energy. This statement is _____ according to the _____ law of thermodynamics.
aliya0001 [1]

Answer:

false, first

Explanation:

The first law of thermodynamics states that energy cannot be created or destroyed. Plants do not create energy, but rather they harness it from the sun. They convert the light energy in the photons of sunlight into chemical energy in the bonds of carbohydrates they make. We get energy from consuming plants when we acquire and break down these chemical bonds in carbohydrates of plants for our cellular processes.
