During which step of meiosis do the pairs of homologous chromosomes split up, but the sister chromatids stay attached?
Degger [83]

Answer:

A) Anaphase I

Explanation:

During the Anaphase I of meiosis, the pairs of homologous chromosome split up. During this phase sister chromatids of each pair is formed and start moving towards the opposite poles. By the end of anaphase  out of each pair of sister chromatids , reaches to the poles of the spindle fibre.  During the metaphse of meiosis the chromosomes start their movements and arrange themselves between the poles and the equator of the spindle.

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.

Distinguish between microtubules and microfilaments. Describe two functions of each kind of structure.
Karo-lina-s [1.5K]

Answer: Microtubules are straight and hollow tubular structures with no limiting membrane arranged in different bundles which are made of globular protein called tubulin while microfilaments are long and fine thread like structures which are made up of non tubular contractile protein called actin and myosin.

Explanation: Microtubules may function alone or join with other proteins to form more complex structures like cilia, flagella or centrioles and perform various functions like

1) Act as conveyer belts which allow movement of granules, vesicles, protein molecules and other organelles like mitochondria to different part of the cell.

2) Form the spindle fibers which separate the chromosomes during mitosis and responsible for the movement of centrioles.

Microfilaments are present throughout the cytoplasm. They are responsible for:

1) Give structure strength and provide resistance to cell against the pulling forces

2) Responsible for cellular movements like contraction, gliding and cytokinesis (partition of cytoplasm during cell division)

In the Linnean taxonomical system _____. The highest level is the family. The Animalia kingdom is the largest. Organisms are nam
Andreas93 [3]

In the Linnean taxonomical system There are more organisms at the species level than at the genus level.

The correct option is D.

Explanation:

Carl Linnaeus is the father of taxonomy. His idea of classification is widely accepted and called as modern classification.

He categorized 7 levels based on the hierarchy as Kingdom, phylum , class, order, family, genus, species.

The Kingdom Animalia is the highest level of classification and species comes last.

The binomial nomenclature by him has made it very popular where distinguished species are categorized and is universal. In binomial nomenclature genus comes first (starts with capital letter) and species comes later (starts with small letter).

One genus will have many species. for example:

African lion  Panthera leo   (genus species)

Asian lion  Panthera leo leo

So one genus will have many species in it.
