Why does Betelgeuse have a much greater absolute magnitude than apparent magnitude?

Biology

<span>The reason is that it is actually 10 parsecs distant from us, so by definition its two magnitudes must be the same. </span>

Which type of deposition creates sandbars?<br><br> A glacial<br> B river<br> C wave<br> D wind
Ede4ka [16]

The correct answer is option C, that is, waves.  

Waves take place at shorelines and are inhibited by the rock walls, dunes, plants, sandbags, and raised structures. The deposition of sand mediated by waves produce beaches and sandbars. The waves continuously erode and shape the coastline.  

The tides, winds, storms, and at certain occasions earthquakes results in the formation of waves. The sandbars also known as trough bars, are formed at the point of breaking of the waves.

Analyze the relationships between the anatomical structures and physiological functions of the muscular system by matching the t
Afina-wow [57]

Answer:

a. Endomysium <u>8. The layer of connective tissue that surrounds an individual </u>muscle fiber

b. Epimysium <u>6. The layer of connective tissue that surrounds a skeletal </u>muscle

c. Fascia <u>3. Connective tissue located between adjacent muscles</u>

d. Fascicle 1<u>2. A small bundle of muscle fibers within a muscle</u>

e. Myosin <u>11. Protein found within a thick filament </u>

f. Perimysium <u>4. The layer of connective tissue that separates a muscle into small bundles</u>

g. Sarcolemma <u>5. The plasma membrane of a muscle fiber</u>

h. Sarcomere <u>7. Unit of alternating light and dark striations between discs (lines)</u>

i. Sarcoplasm <u>2. The cytoplasm of a muscle fiber</u>

j. Sarcoplasmic reticulum <u>9. A cellular organelle in muscle fiber corresponding to the endoplasmic</u>

k. Tendon <u>10. The cordlike part that attaches a muscle to a bone</u>

l. Transverse (T) tubule reticulum <u>1. Membranous channel extending inward from muscle fiber membrane </u>

Explanation:

A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.

The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

In fungi what is the movement response to different types of stimuli in their environment
kap26 [50]

Answer:

the fungi grows in the direction of stimulus

Explanation:

Tropism is a biological phenomenon in which any organism responds in the direction of stimuli.

A fungi when gets in touch or contact of any environmental stimulus , it starts growing or responding in that specific direction is such a way that its growth can be considered as stimulus driven directional growth.

In fungi's basically thigmotropism occur, where it responds  to external mechanical stimulation

Match the wildlife management activities to their description controlling food supply
bezimeni [28]

Description of Wildlife Management Activities is given below.

Explanation:

Wildlife management is concerned with the preservation and improvement of habitats although rewilding is increasingly being used. Techniques can include reforestation, pest control, nitrification and denitrification, irrigation, coppicing and hedge laying.

The most critical aspect of wildlife conservation is habitat management. Habitat loss presents the greatest threat to wildlife.

Five essential elements must be present to provide a viable habitat: food, water, cover, space, and arrangement.

Adult animals that survive hunting can be affected by experiencing mental stress and disruption to the social structure if they are a species that live in a group. ... Hunting with firearms and dogs close to native animals and livestock can also disturb them and cause fear.

Manipulative management involves regulating numbers of animals directly by harvesting or by influencing numbers by altering food supply, habitat, density of predators etc. Custodial management is preventive or protective and minimizes external influences on the population and its habitat.

Wild animals are used in medicine for essential research; wild plants provide a source of drugs, and wild places can help to relieve the tension and stress associated with modern living. Wildlife is also a sensitive indicator of environmental change.

Habitat is the area in which a species lives. Simply stated, habitat is made up of four basic requirements for survival: sufficient space, food, water and shelter. ... Your backyard habitat can provide food, water and shelter even though you may have limited space.

Characteristics of habitats are the abiotic and biotic factors that influence a plant. Among the abiotic factors are chemical and physical values like light, climate, soil composition, soil consistency, exposition to the sun, etc.

Wildlife management can be defined as the manipulation of wildlife populations and habitat to achieve a goal (Sargent and Carter, 1999). Aldo Leopold defined game management as the art of making land produce sustained annual crops of wild game for recreational use.

These are lands which are set aside for the purpose of increasing wildlife numbers by protecting wildlife and key habitat. One of the major goals of a wildlife management areas is to protect at least a minimal number of animals so the population can increase. ... Damage to the habitat then occurs.
