Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?
What does a pyramid of biomass represent? A. Amount of living tissue within a tropic area.
B. Percentage of energy that’s passed through each tropic level.
C. Range of food webs found in one trophies level.
D. Number of total organisms within each trophic level.

Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells. Membrane-bound organelles. Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.
Have a great day friend! :D
Answer:
Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.
Explanation:
ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.Learn more about Organelles here

The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

Factors made the land a place where the first land plants could thrive are abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria as well as deteriorating of rock.
Cyanobacteria were the first photosynthesizing organisms that lived on Earth 3 billion years ago. Cyanobacteria live anywhere on the earth where light and moisture is available i.e. in the open oceans, lakes and streams, in soils, hot and cold deserts, hot springs and salty water.
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase which help in the formation of soil. Oxygen directly take part in the chemical weathering of rocks through the process of oxidation. In this process, oxygen reacts with a substance present in the rock and forms oxides which will result in weathering.

During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps.
Answer: Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
2. Metaphase: Chromosomes line up at the centre of the cell.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.
in which order do plants development
Answer:
According to plant physiologist A. Carl Leopold, the properties of organization seen in a plant are emergent properties which are more than the sum of the individual parts. "The assembly of these tissues and functions into an integrated multicellular organism yields not only the characteristics of the separate parts and processes but also quite a new set of characteristics which would not have been predictable[by whom?] on the basis of examination of the separate parts."[7]

describe the features of the endocrine system for control in the example given.
- endocrine gland
-negative feedback mechanism
-produce hormone -> travel via blood-> target specific cells organs
Please expand these bullet points
Answer:
The endocrine system is a major system in the body composed of glands that secrete hormones, which are substances produced by the body to stimulate an organ or group of cells. The endocrine system controls essential bodily functions, which include movement, sexual development, sensory perception, and even growth.
Explanation:
Hormones are chemicals that are produced by the glands in the endocrine system and coordinate distinct bodily functions by carrying important messages throughout the body. They send signals to receiver cells in organs, muscles, and tissues.
Role of Hormones
Hormones have very essential roles in the body, as they regulate metabolism, growth, and sex development. For example, testosterone and estrogen are sex hormones that are released in the body to initiate sex development during puberty. The rate at which these hormones are produced and released must also be highly controlled for optimal development and growth. Hormones also control levels of hunger or exhaustion. Overall, they are very important in telling the body what to do and how to do it.
Function of Hormones
As previously mentioned, hormones serve several important functions throughout the body. They are responsible for the function of organs, in addition to controlling how the body stores and uses energy. Hormones only target specific organs or cells: for example, thyroid-stimulating hormones are released by the pituitary gland, and only target the thyroid gland. Some hormones can affect several kinds of tissues at once; for instance, the thyroid hormone, produced by the thyroid gland, can affect several bodily functions, such as heart rate and metabolism.

If a mutation occurs such that splicing does not remove one of the introns in a gene, what effect will this have on the protein encoded by that gene
Translation will continue, but it is likely that a nonfunctional or aberrant protein will be made as a result of this effect.
Mutation is described as the alteration in the genetic sequence caused by varying effects. Diseases and exposure to dangerous materials or elements (like x-rays) can cause mutation.
However, when alteration in a genetic sequence is effected such that the splicing that occurs prior to mRNA translation, does not remove a segment of a DNA or RNA molecule (which does not code for protein), and this will disrupt the gene sequence. Although, translation will continue, but the protein synthesised will be a nonfunctional or abnormal one.
