Explanation:
Look at the table for energy used in activities. Ella does 2 hours of dancing a week, plays football for 1 hour a week, and goes swimming for 0.5 hours a week. She has a mass of 55kg. How much extra energy will she need a week in order to do these activities?
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.
Ella, with a mass of 55 kg, does a series of activities in a week.
Let's calculate how much energy she needs for each activity in total.
DancingEllas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.
2 h × 55 kg × 18 kJ/kg.h = 1980 kJ
FootballElla plays 1 hour of football a week, which consumes 25 kJ/kg.h.
1 h × 55 kg × 25 kJ/kg.h = 1375 kJ
SwimmingElla goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.
0.5 h × 55 kg × 20 kJ/kg.h = 550 kJ
Total energy expenditureE = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

You contract an infection from an unknown pathogenic organism. Your doctor conducts a biochemical analysis of the pathogen and discovers that it contains chitin. The pathogen is most likely a
Answer:
Fungus
Explanation:
Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!
Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.
What are pathogens?Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.
Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.
What are fungus pathogens?The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.
Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.
What are the examples of fungus?Ringworm.Vaginal yeast infection.Jock itch. Other fungiThus, we can conclude that the unknown pathogenic organism is fungus because fungus pathogens contain chitin.

Scientists are unable to predict when and where the earthquake will occur precisely, so the government has a duty to issue building codes to ensure that all the structures can withstand earthquakes. I agree with the given statement.
What is Earthquake?An earthquake is a natural disaster which happens when the two blocks of the earth suddenly slip past each other, this causes the tectonic plates to move. The surface where the blocks slip is called the fault or fault plane.
Earthquake damage the buildings and other infrastructure completely which can be fatal for the people living in that area. So, to save life of people government has the duty to issue the buildings code to ensure that all the structures can withstand earthquake.

Briefly summarize the structure of moss.
Mosses are bryophytes, primitive plants believed to be among the first to develop the ability to live on land. Moss plants have no vascular tubes to transfer water or nutrients, and no true stems or roots. Environmental water sources and absorption limit moss plant size.
There may be as many as 15,000 species of mosses. Although unique species of moss grow in dramatically different habitats across the planet – from the arctic to the desert – all have basically the same structure.
Basic Moss SporesThe initial moss plant is a spore given off by the sporophyte that forms at the end of the moss plant’s “stem.” Released spores travel long distances on the wind and may remain viable for decades. Moss spores landing in suitable conditions divide and produce hairy filaments called protonemas, which are like thin plant threads that weave across the growing medium. Sprouting from the spore filaments, gametophytes form, held to the surface by rhizoids.
Main Structure of MossThe main moss structure is the gametophyte, which functions like a moss’s “stem” and “leaves.” A moss "stem" is called the axis, and this part of the moss supports leaf-like structures.
Phyllids are the leaf-like structures that carry out photosynthesis, transforming sunlight into sugars the moss uses for food. Typically arranged in a spiral, moss “leaves” are usually one cell thick with ribs two or more cells thick down their centers. The cells of moss plants contain chlorophyll, the green pigment that is essential for the process of photosynthesis.
Does moss have roots? No, not really. Moss stems end in root-like strands called rhizoids, specialized to hold the moss to its growing surface. Rhizoids anchor moss plants to the surfaces they grow on, but they do not absorb water and nutrients like true plant roots.
Second-Generation GrowthThe second moss structure is really a second generation. Moss reproduction occurs sexually, using separate plants produced at different times. The two separate kinds of moss plants are called gametophytes (which produce gametes) and sporophytes (which produce spores).
Gametophytes are tipped with either inverted cone-shaped areas (archegonia) or male reproductive organs (antheridia). Released sperm (antherizoids) need water since they swim to the archegonium. This is one of the main differences between bryophytes and vascular land plants – mosses need water for their sexual reproduction process.
Fertilization occurs once an antherizoid swims to an archegonium. Sprouting from the gametophyte tip after fertilization, a sporophyte holds itself in place by anchoring a foot in the archegonium.
Spore-Bearing PartsThe sporophyte stalk, called the seta, bears the sporangium (spore capsule) on its tip. One sporangium may produce up to one million spores. Maturing spore capsules are guarded by a covering called the calyptra that shrivels and falls off when the spores are mature. The calyptra can be a distinguishing part of a moss species, and they are often useful in identifying new mosses.
A cap called the operculum tops the capsule's opening under the calyptra. The capsule opening (peristome) can have teeth that help hold it closed. Matured spores are released when the capsule top ruptures and drift off to form new plants. Like the calyptra, the operculum and peristome of some moss species are highly identifiable.
Wether the apple has a taproot or a fibrous root
Answer:
taproot
Explanation:
Apple trees roots consist of a deep taproot and lateral fibrous roots. The taproot is analogous to the carrot, which is a taproot. Lateral fibrous roots can extent to more than twice the spread of the canopy of the apple tree and are influenced by soil, water availability and competition from the roots of other plants.
Answer:Tap roots.

Answer:
How does the cell membrane and mitochondria work together to make energy?
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.
