Select all the correct answers.In which three ways can we use biomass as a source of energy?

by extracting hydrogen from it
by converting it into liquid fuels
by making suitable bacteria act on it
by burning it directly
by mixing it with petroleum-based fuels

Answers

Answer 1
Answer:

Answer:

The correct ways to use biomass as a source of energy are:

By converting it into liquid fuels: Biomass can be processed into liquid biofuels like biodiesel and bioethanol, which can be used as alternatives to fossil fuels.

By burning it directly: Biomass can be burned directly as a source of heat and energy. This is often done in the form of wood, agricultural residues, or dedicated energy crops.

By making suitable bacteria act on it: Biomass can be used to produce biogas through a process called anaerobic digestion, where bacteria break down organic materials to generate methane, a valuable energy source.

Ryan hit a baseball with an acceleration of 20 m/s2. The mass of the baseball is 0.5 kg. What is the force?

Answers

Well to find the answer for force, the formula is mass X acceleration.
So, 20m/s² X 0.5kg = 10kg-m/s².
But, because we measure force in Newtons, we have to change the units (kg/m/s²) to Newtons.
1N (newton) equals to 1kg-m/s² and because we had 10, your answer is 
10N

Which of the following forms an important component of phloem tissue?A. tracheids

B.
vessels

C. companion cells

Answers

Answer: The correct answer is- C) Companion cells.

Phloem tissue is a complex conducting tissue that is present in the vascular plants and responsible for the transport of organic compound such as carbohydrates and proteins from leaves to the rest part of the plant.

The various components of phloem tissue are- Sieve element, Companion cells, phloem parenchyma, phloem fiber.

Companion cells are specialized cells ( present in association of sieve element) that perform various metabolic reactions and responsible for cellular activities. They help in loading and unloading of carbohydrate into sieve element.      
C. Companion cells. THe vessels are for blood flow, Tracheids are elongated cells in the xylem of vascular plants that serve in the transport of water and mineral salts. 

Mammals reproduce through a process called sexual reproduction. During this process, which involves two parents,A. a female egg cell combines with a male sperm cell to make an offspring that is identical to one of the parents.

B. a female egg cell and a male sperm cell each develop separately into an offspring that is different from both parents.

C. a female egg cell and a male sperm cell each develop separately into an offspring that is identical to its parent.

D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents.

Answers

D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents. Gametes are produced by meiosis, and the source of genetic variation during sexual reproduction comes from crossing over of tetrads at chiasma during prophase I, independent assortment, and random fertilization. These gametes (egg and sperm) then combine to form a genetically different offspring.

Answer:

D- a female egg cell combines with a male sperm cell to make an offspring that is different from both parents

Where should the biosphere label appear in the system model? Use reasoning to explain your answer.

Answers

Answer:

Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.

In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.

The biosphere label should be appeared in the system model that contains geological sphere of the earth.

What is biosphere?

It is the one of the sphere that comprise of the geological sphere of the earth like the geosphere, hydrosphere and atmosphere. In this, there should be the existance and the interaction of the living organism.

Here in the given model, there should be the human, fished, etc should be labeled as the biosphere rather than the atmosphere or without the atmosphere.

Which is a possible outcome of global warming

Answers

Extinction to different animal species, could vause forest fires and destroy animal habotats therefor becoming extinct, could over heat water causing algae to form on the top not letting sunlight through for plants to photosynthesize which doesnt give fish the nutrients they need to survive.
2 possible outcomes of global warming is climate change and rising temperatures as well. Hoped that helped!!!
